+Description: Some Samsung laptops have different "performance levels"
+ that are can be modified by a function key, and by this
+ sysfs file. These values don't always make a whole lot
+ of sense, but some users like to modify them to keep
+ their fans quiet at all costs. Reading from this file
+ will show the current performance level. Writing to the
+ file can change this value.
+ Valid options:
+ "silent"
+ "normal"
+ "overclock"
+ Note that not all laptops support all of these options.
+ Specifically, not all support the "overclock" option,
+ and it's still unknown if this value even changes
+ anything, other than making the user feel a bit better.

+Ioctls
+======
+
+There is some Ext4 specific functionality which can be accessed by applications
+through the system call interfaces. The list of all Ext4 specific ioctls are
+shown in the table below.
+
+Table of Ext4 specific ioctls
+..............................................................................
+ Ioctl Description
+ EXT4_IOC_GETFLAGS Get additional attributes associated with inode.
+ The ioctl argument is an integer bitfield, with
+ bit values described in ext4.h. This ioctl is an
+ alias for FS_IOC_GETFLAGS.
+
+ EXT4_IOC_SETFLAGS Set additional attributes associated with inode.
+ The ioctl argument is an integer bitfield, with
+ bit values described in ext4.h. This ioctl is an
+ alias for FS_IOC_SETFLAGS.
+
+ EXT4_IOC_GETVERSION
+ EXT4_IOC_GETVERSION_OLD
+ Get the inode i_generation number stored for
+ each inode. The i_generation number is normally
+ changed only when new inode is created and it is
+ particularly useful for network filesystems. The
+ '_OLD' version of this ioctl is an alias for
+ FS_IOC_GETVERSION.
+
+ EXT4_IOC_SETVERSION
+ EXT4_IOC_SETVERSION_OLD
+ Set the inode i_generation number stored for
+ each inode. The '_OLD' version of this ioctl
+ is an alias for FS_IOC_SETVERSION.
+
+ EXT4_IOC_GROUP_EXTEND This ioctl has the same purpose as the resize
+ mount option. It allows to resize filesystem
+ to the end of the last existing block group,
+ further resize has to be done with resize2fs,
+ either online, or offline. The argument points
+ to the unsigned logn number representing the
+ filesystem new block count.
+
+ EXT4_IOC_MOVE_EXT Move the block extents from orig_fd (the one
+ this ioctl is pointing to) to the donor_fd (the
+ one specified in move_extent structure passed
+ as an argument to this ioctl). Then, exchange
+ inode metadata between orig_fd and donor_fd.
+ This is especially useful for online
+ defragmentation, because the allocator has the
+ opportunity to allocate moved blocks better,
+ ideally into one contiguous extent.
+
+ EXT4_IOC_GROUP_ADD Add a new group descriptor to an existing or
+ new group descriptor block. The new group
+ descriptor is described by ext4_new_group_input
+ structure, which is passed as an argument to
+ this ioctl. This is especially useful in
+ conjunction with EXT4_IOC_GROUP_EXTEND,
+ which allows online resize of the filesystem
+ to the end of the last existing block group.
+ Those two ioctls combined is used in userspace
+ online resize tool (e.g. resize2fs).
+
+ EXT4_IOC_MIGRATE This ioctl operates on the filesystem itself.
+ It converts (migrates) ext3 indirect block mapped
+ inode to ext4 extent mapped inode by walking
+ through indirect block mapping of the original
+ inode and converting contiguous block ranges
+ into ext4 extents of the temporary inode. Then,
+ inodes are swapped. This ioctl might help, when
+ migrating from ext3 to ext4 filesystem, however
+ suggestion is to create fresh ext4 filesystem
+ and copy data from the backup. Note, that
+ filesystem has to support extents for this ioctl
+ to work.
+
+ EXT4_IOC_ALLOC_DA_BLKS Force all of the delay allocated blocks to be
+ allocated to preserve application-expected ext3
+ behaviour. Note that this will also start
+ triggering a write of the data blocks, but this
+ behaviour may change in the future as it is
+ not necessary and has been done this way only
+ for sake of simplicity.
