+ * The inode->i_version field:
+ * ---------------------------
+ * The change attribute (i_version) is mandated by NFSv4 and is mostly for
+ * knfsd, but is also used for other purposes (e.g. IMA). The i_version must
+ * appear different to observers if there was a change to the inode's data or
+ * metadata since it was last queried.
+ *
+ * Observers see the i_version as a 64-bit number that never decreases. If it
+ * remains the same since it was last checked, then nothing has changed in the
+ * inode. If it's different then something has changed. Observers cannot infer
+ * anything about the nature or magnitude of the changes from the value, only
+ * that the inode has changed in some fashion.
+ *
+ * Not all filesystems properly implement the i_version counter. Subsystems that
+ * want to use i_version field on an inode should first check whether the
+ * filesystem sets the SB_I_VERSION flag (usually via the IS_I_VERSION macro).
+ *
+ * Those that set SB_I_VERSION will automatically have their i_version counter
+ * incremented on writes to normal files. If the SB_I_VERSION is not set, then
+ * the VFS will not touch it on writes, and the filesystem can use it how it
+ * wishes. Note that the filesystem is always responsible for updating the
+ * i_version on namespace changes in directories (mkdir, rmdir, unlink, etc.).
+ * We consider these sorts of filesystems to have a kernel-managed i_version.
+ *
+ * It may be impractical for filesystems to keep i_version updates atomic with
+ * respect to the changes that cause them.  They should, however, guarantee
+ * that i_version updates are never visible before the changes that caused
+ * them.  Also, i_version updates should never be delayed longer than it takes
+ * the original change to reach disk.
+ *
+ * This implementation uses the low bit in the i_version field as a flag to
+ * track when the value has been queried. If it has not been queried since it
+ * was last incremented, we can skip the increment in most cases.
+ *
+ * In the event that we're updating the ctime, we will usually go ahead and
+ * bump the i_version anyway. Since that has to go to stable storage in some
+ * fashion, we might as well increment it as well.
+ *
+ * With this implementation, the value should always appear to observers to
+ * increase over time if the file has changed. It's recommended to use
+ * inode_eq_iversion() helper to compare values.
+ *
+ * Note that some filesystems (e.g. NFS and AFS) just use the field to store
+ * a server-provided value (for the most part). For that reason, those
+ * filesystems do not set SB_I_VERSION. These filesystems are considered to
+ * have a self-managed i_version.
+ *
+ * Persistently storing the i_version
+ * ----------------------------------
+ * Queries of the i_version field are not gated on them hitting the backing
+ * store. It's always possible that the host could crash after allowing
+ * a query of the value but before it has made it to disk.
+ *
+ * To mitigate this problem, filesystems should always use
+ * inode_set_iversion_queried when loading an existing inode from disk. This
+ * ensures that the next attempted inode increment will result in the value
+ * changing.
+ *
+ * Storing the value to disk therefore does not count as a query, so those
+ * filesystems should use inode_peek_iversion to grab the value to be stored.
+ * There is no need to flag the value as having been queried in that case.
+ */
+
+/*
+ * We borrow the lowest bit in the i_version to use as a flag to tell whether

- *     struct a {

+ * can use some of the space in struct page for your own purposes.

+ * Pages that were once in the page cache may be found under the RCU lock
+ * even after they have been recycled to a different purpose.  The page
+ * cache reads and writes some of the fields in struct page to pin the
+ * page before checking that it's still in the page cache.  It is vital
+ * that all users of struct page:
+ * 1. Use the first word as PageFlags.
+ * 2. Clear or preserve bit 0 of page->compound_head.  It is used as
+ *    PageTail for compound pages, and the page cache must not see false
+ *    positives.  Some users put a pointer here (guaranteed to be at least
+ *    4-byte aligned), other users avoid using the field altogether.
+ * 3. page->_refcount must either not be used, or must be used in such a
+ *    way that other CPUs temporarily incrementing and then decrementing the
+ *    refcount does not cause problems.  On receiving the page from
+ *    alloc_pages(), the refcount will be positive.
+ * 4. Either preserve page->_mapcount or restore it to -1 before freeing it.
+ *
+ * If you allocate pages of order > 0, you can use the fields in the struct
+ * page associated with each page, but bear in mind that the pages may have
+ * been inserted individually into the page cache, so you must use the above
+ * four fields in a compatible way for each struct page.
  *
- * The objects in struct page are organized in double word blocks in
- * order to allows us to use atomic double word operations on portions
- * of struct page. That is currently only used by slub but the arrangement
- * allows the use of atomic double word operations on the flags/mapping
- * and lru list pointers also.
+ * SLUB uses cmpxchg_double() to atomically update its freelist and
+ * counters.  That requires that freelist & counters be adjacent and
+ * double-word aligned.  We align all struct pages to double-word
+ * boundaries, and ensure that 'freelist' is aligned within the

+ * cleared by the drivers as the driver core will take care of that.
+ *
+ * NEVER_SKIP: Do not skip all system suspend/resume callbacks for the device.
+ * SMART_PREPARE: Check the return value of the driver's ->prepare callback.
+ * SMART_SUSPEND: No need to resume the device from runtime suspend.
+ * LEAVE_SUSPENDED: Avoid resuming the device during system resume if possible.
+ *
+ * Setting SMART_PREPARE instructs bus types and PM domains which may want
+ * system suspend/resume callbacks to be skipped for the device to return 0 from
+ * their ->prepare callbacks if the driver's ->prepare callback returns 0 (in
+ * other words, the system suspend/resume callbacks can only be skipped for the
+ * device if its driver doesn't object against that).  This flag has no effect
+ * if NEVER_SKIP is set.
+ *
+ * Setting SMART_SUSPEND instructs bus types and PM domains which may want to
+ * runtime resume the device upfront during system suspend that doing so is not
+ * necessary from the driver's perspective.  It also may cause them to skip
+ * invocations of the ->suspend_late and ->suspend_noirq callbacks provided by
+ * the driver if they decide to leave the device in runtime suspend.
+ *
+ * Setting LEAVE_SUSPENDED informs the PM core and middle-layer code that the

+ *
+ * This function callback prototype, provided by the client of the demux API,
+ * is called from the demux code. The function is only called when filtering
+ * on a TS feed has been enabled using the start_filtering\(\) function at
+ * the &dmx_demux.
+ * Any TS packets that match the filter settings are copied to a circular
+ * buffer. The filtered TS packets are delivered to the client using this
+ * callback function.
+ * It is expected that the @buffer1 and @buffer2 callback parameters point to
+ * addresses within the circular buffer, but other implementations are also
+ * possible. Note that the called party should not try to free the memory
+ * the @buffer1 and @buffer2 parameters point to.
+ *
+ * When this function is called, the @buffer1 parameter typically points to
+ * the start of the first undelivered TS packet within a circular buffer.
+ * The @buffer2 buffer parameter is normally NULL, except when the received
+ * TS packets have crossed the last address of the circular buffer and
+ * "wrapped" to the beginning of the buffer. In the latter case the @buffer1
+ * parameter would contain an address within the circular buffer, while the
+ * @buffer2 parameter would contain the first address of the circular buffer.
+ * The number of bytes delivered with this function (i.e. @buffer1_length +
+ * @buffer2_length) is usually equal to the value of callback_length parameter
+ * given in the set() function, with one exception: if a timeout occurs before
+ * receiving callback_length bytes of TS data, any undelivered packets are
+ * immediately delivered to the client by calling this function. The timeout
+ * duration is controlled by the set() function in the TS Feed API.
+ *
+ * If a TS packet is received with errors that could not be fixed by the
+ * TS-level forward error correction (FEC), the Transport_error_indicator
+ * flag of the TS packet header should be set. The TS packet should not be
+ * discarded, as the error can possibly be corrected by a higher layer
+ * protocol. If the called party is slow in processing the callback, it
+ * is possible that the circular buffer eventually fills up. If this happens,
+ * the demux driver should discard any TS packets received while the buffer
+ * is full and return -EOVERFLOW.
+ *
+ * The type of data returned to the callback can be selected by the
+ * &dmx_ts_feed.@set function. The type parameter decides if the raw
+ * TS packet (TS_PACKET) or just the payload (TS_PACKET|TS_PAYLOAD_ONLY)
+ * should be returned. If additionally the TS_DECODER bit is set the stream
+ * will also be sent to the hardware MPEG decoder.

- *			(if available).
- *
- * @code_length:	length of the remote control key code expressed in bits.
- *
- * @buffer_size:	Number of FIFO buffers with @chunk_size size. If zero,

- *
- * @features:		lirc compatible hardware features, like LIRC_MODE_RAW,
- *			LIRC_CAN\_\*, as defined at include/media/lirc.h.
- *
- * @chunk_size:		Size of each FIFO buffer.
- *
- * @data:		it may point to any driver data and this pointer will

- *
- * @fops:		file_operations for drivers which don't fit the current
- *			driver model.
- *			Some ioctl's can be directly handled by lirc_dev if the

- * Overview:
- *
- * Events are subscribed per-filehandle. An event specification consists of a
- * type and is optionally associated with an object identified through the
- * 'id' field. So an event is uniquely identified by the (type, id) tuple.
- *
- * The v4l2-fh struct has a list of subscribed events. The v4l2_subscribed_event
- * struct is added to that list, one for every subscribed event.
- *
- * Each v4l2_subscribed_event struct ends with an array of v4l2_kevent structs.
- * This array (ringbuffer, really) is used to store any events raised by the
- * driver. The v4l2_kevent struct links into the 'available' list of the
- * v4l2_fh struct so VIDIOC_DQEVENT will know which event to dequeue first.
- *
- * Finally, if the event subscription is associated with a particular object
- * such as a V4L2 control, then that object needs to know about that as well
- * so that an event can be raised by that object. So the 'node' field can
- * be used to link the v4l2_subscribed_event struct into a list of that
- * object.
- *
- * So to summarize:
- *
- * struct v4l2_fh has two lists: one of the subscribed events, and one of the
- * pending events.
- *
- * struct v4l2_subscribed_event has a ringbuffer of raised (pending) events of
- * that particular type.
- *
- * If struct v4l2_subscribed_event is associated with a specific object, then
- * that object will have an internal list of struct v4l2_subscribed_event so
- * it knows who subscribed an event to that object.

+/* Limits on Hop-by-Hop and Destination options.
+ *
+ * Per RFC8200 there is no limit on the maximum number or lengths of options in
+ * Hop-by-Hop or Destination options other then the packet must fit in an MTU.
+ * We allow configurable limits in order to mitigate potential denial of
+ * service attacks.
+ *
+ * There are three limits that may be set:
+ *   - Limit the number of options in a Hop-by-Hop or Destination options
+ *     extension header
+ *   - Limit the byte length of a Hop-by-Hop or Destination options extension
+ *     header
+ *   - Disallow unknown options
+ *
+ * The limits are expressed in corresponding sysctls:
+ *
+ * ipv6.sysctl.max_dst_opts_cnt
+ * ipv6.sysctl.max_hbh_opts_cnt
+ * ipv6.sysctl.max_dst_opts_len
+ * ipv6.sysctl.max_hbh_opts_len
+ *
+ * max_*_opts_cnt is the number of TLVs that are allowed for Destination
+ * options or Hop-by-Hop options. If the number is less than zero then unknown
+ * TLVs are disallowed and the number of known options that are allowed is the
+ * absolute value. Setting the value to INT_MAX indicates no limit.
+ *
+ * max_*_opts_len is the length limit in bytes of a Destination or
+ * Hop-by-Hop options extension header. Setting the value to INT_MAX
+ * indicates no length limit.
+ *
+ * If a limit is exceeded when processing an extension header the packet is
+ * silently discarded.

+ * DOC: XDP RX-queue information
+ *
+ * The XDP RX-queue info (xdp_rxq_info) is associated with the driver
+ * level RX-ring queues.  It is information that is specific to how
+ * the driver have configured a given RX-ring queue.
+ *
+ * Each xdp_buff frame received in the driver carry a (pointer)
+ * reference to this xdp_rxq_info structure.  This provides the XDP
+ * data-path read-access to RX-info for both kernel and bpf-side
+ * (limited subset).
+ *
+ * For now, direct access is only safe while running in NAPI/softirq
+ * context.  Contents is read-mostly and must not be updated during
+ * driver NAPI/softirq poll.
+ *
+ * The driver usage API is a register and unregister API.
+ *
+ * The struct is not directly tied to the XDP prog.  A new XDP prog
+ * can be attached as long as it doesn't change the underlying
+ * RX-ring.  If the RX-ring does change significantly, the NIC driver
+ * naturally need to stop the RX-ring before purging and reallocating
+ * memory.  In that process the driver MUST call unregistor (which
+ * also apply for driver shutdown and unload).  The register API is
+ * also mandatory during RX-ring setup.

-* The IXJCTL_REC_DEPTH command sets the internal buffer depth of the DSP.
-* Setting a lower depth reduces latency, but increases the demand of the
-* application to service the driver without frame loss.  The DSP has 480
-* bytes of physical buffer memory for the record channel so the true
-* maximum limit is determined by how many frames will fit in the buffer.
-*
-* 1 uncompressed (480 byte) 16-bit linear frame.

-* 15 TrueSpeech 8.5 frames.

-*
-* The default in the driver is currently set to 2 frames.
-*
-* The IXJCTL_REC_VOLUME and IXJCTL_PLAY_VOLUME commands both use a Q8
-* number as a parameter, 0x100 scales the signal by 1.0, 0x200 scales the
-* signal by 2.0, 0x80 scales the signal by 0.5.  No protection is given
-* against over-scaling, if the multiplication factor times the input
-* signal exceeds 16 bits, overflow distortion will occur.  The default
-* setting is 0x100 (1.0).

-*
-* The IXJCTL_TONE_CADENCE ioctl defines tone sequences used for various
-* Call Progress Tones (CPT).  This is accomplished by setting up an array of
-* IXJ_CADENCE_ELEMENT structures that sequentially define the states of
-* the tone sequence.  The tone_on_time and tone_off time are in
-* 250 microsecond intervals.  A pointer to this array is passed to the
-* driver as the ce element of an IXJ_CADENCE structure.  The elements_used
-* must be set to the number of IXJ_CADENCE_ELEMENTS in the array.  The
-* termination variable defines what to do at the end of a cadence, the
-* options are to play the cadence once and stop, to repeat the last
-* element of the cadence indefinitely, or to repeat the entire cadence
-* indefinitely.  The ce variable is a pointer to the array of IXJ_TONE
-* structures.  If the freq0 variable is non-zero, the tone table contents
-* for the tone_index are updated to the frequencies and gains defined.  It
-* should be noted that DTMF tones cannot be reassigned, so if DTMF tone
-* table indexes are used in a cadence the frequency and gain variables will
-* be ignored.
-*
-* If the array elements contain frequency parameters the driver will
-* initialize the needed tone table elements and begin playing the tone,
-* there is no preset limit on the number of elements in the cadence.  If
-* there is more than one frequency used in the cadence, sequential elements
-* of different frequencies MUST use different tone table indexes.  Only one
-* cadence can be played at a time.  It is possible to build complex
-* cadences with multiple frequencies using 2 tone table indexes by
-* alternating between them.
