Merge branch 'for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jack/linux-fs
Pull ext3, udf, quota fixes from Jan Kara:
"Some ext3 & quota cleanups and couple of udf fixes"
* 'for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jack/linux-fs:
quota: Use the pre-processor to compile out quotactl_cmd_write when !CONFIG_BLOCK
ext3: drop if around WARN_ON
ext3: get rid of the duplicate code on ext3_fill_super
udf: remove un-needed variable from inode_getblk
udf: don't increment lenExtents while writing to a hole
udf: fix memory leak while allocating blocks during write
