Merge branch 'for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jack/linux-fs
Pull ext2, ext3, udf updates from Jan Kara:
"Several UDF fixes, a support for UDF extent cache, and couple of ext2
and ext3 cleanups and minor fixes"
* 'for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jack/linux-fs:
Ext2: remove the static function release_blocks to optimize the kernel
Ext2: mark inode dirty after the function dquot_free_block_nodirty is called
Ext2: remove the overhead check about sb in the function ext2_new_blocks
udf: Remove unused s_extLength from udf_bitmap
udf: Make s_block_bitmap standard array
udf: Fix bitmap overflow on large filesystems with small block size
udf: add extent cache support in case of file reading
udf: Write LVID to disk after opening / closing
Ext3: return ENOMEM rather than EIO if sb_getblk fails
Ext2: return ENOMEM rather than EIO if sb_getblk fails
Ext3: use unlikely to improve the efficiency of the kernel
Ext2: use unlikely to improve the efficiency of the kernel
Ext3: add necessary check in case IO error happens
Ext2: free memory allocated and forget buffer head when io error happens
ext3: Fix memory leak when quota options are specified multiple times
ext3, ext4, ocfs2: remove unused macro NAMEI_RA_INDEX
