Merge tag 'ext4_for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tytso/ext4
Pull ext4 updates from Ted Ts'o:
"Added new ext4 debugging ioctls to allow userspace to get information
about the state of the extent status cache.
Dropped workaround for pre-1970 dates which were encoded incorrectly
in pre-4.4 kernels. Since both the kernel correctly generates, and
e2fsck detects and fixes this issue for the past four years, it'e time
to drop the workaround. (Also, it's not like files with dates in the
distant past were all that common in the first place.)
A lot of miscellaneous bug fixes and cleanups, including some ext4
Documentation fixes. Also included are two minor bug fixes in
fs/unicode"

The extra space between the end of the inode structure and the end of the inode record can be used to store extended attributes. Each inode record can be as large as the filesystem block size, though this is not terribly efficient. |
