Merge tag 'ext4_for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tytso/ext4
Pull ext4 update from Ted Ts'o:
"There are two major features for this merge window. The first is
inline data, which allows small files or directories to be stored in
the in-inode extended attribute area. (This requires that the file
system use inodes which are at least 256 bytes or larger; 128 byte
inodes do not have any room for in-inode xattrs.)
The second new feature is SEEK_HOLE/SEEK_DATA support. This is
enabled by the extent status tree patches, and this infrastructure
will be used to further optimize ext4 in the future.
Beyond that, we have the usual collection of code cleanups and bug
fixes."
