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." * tag 'ext4_for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tytso/ext4: (63 commits) ext4: zero out inline data using memset() instead of empty_zero_page ext4: ensure Inode flags consistency are checked at build time ext4: Remove CONFIG_EXT4_FS_XATTR ext4: remove unused variable from ext4_ext_in_cache() ext4: remove redundant initialization in ext4_fill_super() ext4: remove redundant code in ext4_alloc_inode() ext4: use sync_inode_metadata() when syncing inode metadata ext4: enable ext4 inline support ext4: let fallocate handle inline data correctly ext4: let ext4_truncate handle inline data correctly ext4: evict inline data out if we need to strore xattr in inode ext4: let fiemap work with inline data ext4: let ext4_rename handle inline dir ext4: let empty_dir handle inline dir ext4: let ext4_delete_entry() handle inline data ext4: make ext4_delete_entry generic ext4: let ext4_find_entry handle inline data ext4: create a new function search_dir ext4: let ext4_readdir handle inline data ext4: let add_dir_entry handle inline data properly ...
