Pull erofs updates from Gao Xiang: "In this cycle, tail-packing data inline for compressed files is now supported so that tail pcluster can be stored and read together with inode metadata in order to save data I/O and storage space. In addition to that, to prepare for the upcoming subpage, folio and fscache features, we also introduce meta buffers to get rid of erofs_get_meta_page() since it was too close to the page itself. In addition, in order to show supported kernel features and control sync decompression strategy, new sysfs nodes are introduced in this cycle as well. Summary: - add sysfs interface and a sysfs node to control sync decompression - add tail-packing inline support for compressed files - get rid of erofs_get_meta_page()" * tag 'erofs-for-5.17-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/xiang/erofs: erofs: use meta buffers for zmap operations erofs: use meta buffers for xattr operations erofs: use meta buffers for super operations erofs: use meta buffers for inode operations erofs: introduce meta buffer operations erofs: add on-disk compressed tail-packing inline support erofs: support inline data decompression erofs: support unaligned data decompression erofs: introduce z_erofs_fixup_insize erofs: tidy up z_erofs_lz4_decompress erofs: clean up erofs_map_blocks tracepoints erofs: Replace zero-length array with flexible-array member erofs: add sysfs node to control sync decompression strategy erofs: add sysfs interface erofs: rename lz4_0pading to zero_padding
2022-01-11Merge tag 'fs.idmapped.v5.17' of git://git.kernel.org/pub/scm/linux/kernel/git/brauner/linuxLinus Torvalds1-72/+0
Pull fs idmapping updates from Christian Brauner: "This contains the work to enable the idmapping infrastructure to support idmapped mounts of filesystems mounted with an idmapping. In addition this contains various cleanups that avoid repeated open-coding of the same functionality and simplify the code in quite a few places. We also finish the renaming of the mapping helpers we started a few kernel releases back and move them to a dedicated header to not continue polluting the fs header needlessly with low-level idmapping helpers. With this series the fs header only contains idmapping helpers that interact with fs objects. Currently we only support idmapped mounts for filesystems mounted without an idmapping themselves. This was a conscious decision mentioned in multiple places (cf. [1]). As explained at length in [3] it is perfectly fine to extend support for idmapped mounts to filesystem's mounted with an idmapping should the need arise. The need has been there for some time now (cf. [2]). Before we can port any filesystem that is mountable with an idmapping to support idmapped mounts in the coming cycles, we need to first extend the mapping helpers to account for the filesystem's idmapping. This again, is explained at length in our documentation at [3] and also in the individual commit messages so here's an overview. Currently, the low-level mapping helpers implement the remapping algorithms described in [3] in a simplified manner as we could rely on the fact that all filesystems supporting idmapped mounts are mounted without an idmapping. In contrast, filesystems mounted with an idmapping are very likely to not use an identity mapping and will instead use a non-identity mapping. So the translation step from or into the filesystem's idmapping in the remapping algorithm cannot be skipped for such filesystems. Non-idmapped filesystems and filesystems not supporting idmapped mounts are unaffected by this change as the remapping algorithms can take the same shortcut as before. If the low-level helpers detect that they are dealing with an idmapped mount but the underlying filesystem is mounted without an idmapping we can rely on the previous shortcut and can continue to skip the translation step from or into the filesystem's idmapping. And of course, if the low-level helpers detect that they are not dealing with an idmapped mount they can simply return the relevant id unchanged; no remapping needs to be performed at all. These checks guarantee that only the minimal amount of work is performed. As before, if idmapped mounts aren't used the low-level helpers are idempotent and no work is performed at all" Link: 2ca4dcc4909d ("fs/mount_setattr: tighten permission checks") [1] Link: https://github.com/containers/podman/issues/10374 [2] Link: Documentations/filesystems/idmappings.rst [3] Link: a65e58e791a1 ("fs: document and rename fsid helpers") [4] * tag 'fs.idmapped.v5.17' of git://git.kernel.org/pub/scm/linux/kernel/git/brauner/linux: fs: support mapped mounts of mapped filesystems fs: add i_user_ns() helper fs: port higher-level mapping helpers fs: remove unused low-level mapping helpers fs: use low-level mapping helpers docs: update mapping documentation fs: account for filesystem mappings fs: tweak fsuidgid_has_mapping() fs: move mapping helpers fs: add is_idmapped_mnt() helper

Pull gpio updates from Bartosz Golaszewski: "The gpio-sim module is back, this time without any changes to configfs. This results in a less elegant user-space interface but I never got any follow-up on the committable items and didn't want to delay this module for several more months. Other than that we have support for several new models and some support going away. We started working on converting GPIO drivers to using fwnode exclusively in order to limit references to OF symbols to gpiolib-of.c exclusively. We also have regular tweaks and improvements all over the place. Summary: - new testing module: gpio-sim that is scheduled to replace gpio-mockup - initial changes aiming at converting all GPIO drivers to using the fwnode interface and limiting any references to OF symbols to gpiolib-of.c - add support for Tegra234 and Tegra241 to gpio-tegra186 - add support for new models (SSD201 and SSD202D) to gpio-msc313 - add basic support for interrupts to gpio-aggregator - add support for AMDIF031 HID device to gpio-amdpt - drop support for unused platforms in gpio-xlp - cleanup leftovers from the removal of the legacy Samsung Exynos GPIO driver - use raw spinlocks in gpio-aspeed and gpio-aspeed-sgpio to make PREEMPT_RT happy - generalize the common 'ngpios' device property by reading it in the core gpiolib code so that we can remove duplicate reads from drivers - allow line names from device properties to override names set by drivers - code shrink in gpiod_add_lookup_table() - add new model to the DT bindings for gpio-vf610 - convert DT bindings for tegra devices to YAML - improvements to interrupt handling in gpio-rcar and gpio-rockchip - updates to intel drivers from Andy (details in the merge commit) - some minor tweaks, improvements and coding-style fixes all around the subsystem" * tag 'gpio-updates-for-v5.17' of git://git.kernel.org/pub/scm/linux/kernel/git/brgl/linux: (59 commits) gpio: rcar: Propagate errors from devm_request_irq() gpio: rcar: Use platform_get_irq() to get the interrupt gpio: ts5500: Use platform_get_irq() to get the interrupt gpio: dwapb: Switch to use fwnode instead of of_node gpiolib: acpi: make fwnode take precedence in struct gpio_chip dt-bindings: gpio: samsung: drop unused bindings gpio: max3191x: Use bitmap_free() to free bitmap gpio: regmap: Switch to use fwnode instead of of_node gpio: tegra186: Add support for Tegra241 dt-bindings: gpio: Add Tegra241 support gpio: brcmstb: Use local variable to access OF node gpio: Remove unused local OF node pointers gpio: sim: add missing fwnode_handle_put() in gpio_sim_probe() gpio: msc313: Add support for SSD201 and SSD202D gpio: msc313: Code clean ups dt-bindings: gpio: msc313: Add offsets for ssd20xd dt-bindings: gpio: msc313: Add compatible for ssd20xd gpio: sim: fix uninitialized ret variable gpio: Propagate firmware node from a parent device gpio: Setup parent device and get rid of unnecessary of_node assignment ...

2022-01-10Documentation: remove trivial treeJiri Kosina5-101/+0
As has been discussed some time ago on ksumitt-discuss@ mailinglist, the need for trivial tree diminished over time as all the tooling and processess became much more mature and it's quite natural these days for trivial patches to flow through subsystem trees anyway, so the spin-off of a trivial tree doesn't make sense any more, and is not worth the merge conflicts it might sometimes create. So remove any mentions of it from kernel documentation for good. Link: https://lore.kernel.org/all/nycvar.YFH.7.76.2104222334290.18270@cbobk.fhfr.pm/ Signed-off-by: Jiri Kosina <jkosina@suse.cz>

2022-01-07net: ena: Update LLQ header length in ena documentationArthur Kiyanovski1-1/+1
LLQ entry length is 128 bytes. Therefore the maximum header in the entry is calculated by: tx_max_header_size = LLQ_ENTRY_SIZE - DESCRIPTORS_NUM_BEFORE_HEADER * 16 = 128 - 2 * 16 = 96 This patch updates the documentation so that it states the correct max header length.

Our documentation encourages the use of list-table formats, but that advice runs counter to the objective of keeping the plain-text documentation as useful and readable as possible.

2022-01-07docs: automarkup.py: Fix invalid HTML link output and broken URI fragmentsJames Clark1-7/+18
Since commit d18b01789ae5 ("docs: Add automatic cross-reference for documentation pages"), references that were already explicitly defined with "ref:" and referred to other pages with a path have been doubled. This is reported as the following error by Firefox: Start tag "a" seen but an element of the same type was already open. End tag "a" violates nesting rules. As well as the invalid HTML, this also obscures the URI fragment links to subsections because the second link overrides the first. For example on the page admin-guide/hw-vuln/mds.html the last link should be to the "Default Mitigations" subsection using a # URI fragment: admin-guide/hw-vuln/l1tf.html#default-mitigations But it is obsured by a second link to the whole page: admin-guide/hw-vuln/l1tf.html The full HTML with the double <a> tags looks like this: <a class="reference internal" href="l1tf.html#default-mitigations"> <span class="std std-ref"> <a class="reference internal" href="l1tf.html"> <span class="doc">L1TF - L1 Terminal Fault</span> </a> </span> </a> After this commit, there is only a single link: <a class="reference internal" href="l1tf.html#default-mitigations"> <span class="std std-ref">Documentation/admin-guide/hw-vuln//l1tf.rst</span> </a> Now that the second link is removed, the browser correctly jumps to the default-mitigations subsection when clicking the link. The fix is to check that nodes in the document to be modified are not already references. A reference is counted as any text that is a descendant of a reference type node. Only plain text should be converted to new references, otherwise the doubling occurs. Testing ======= * Test that the build stdout is the same (ignoring ordering), and that no new warnings are printed. * Diff all .html files and check that the only modifications occur to the bad double links. * The auto linking of bare references to pages without "ref:" is still working.
