Merge branch 'for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jack/linux-fs
Pull ext3, UDF, and quota fixes from Jan Kara: "A couple of ext3 & UDF fixes and also one improvement in quota locking." * 'for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jack/linux-fs: ext3: fix start and len arguments handling in ext3_trim_fs() udf: Fix deadlock in udf_release_file() udf: Fix file entry logicalBlocksRecorded udf: Fix handling of i_blocks quota: Make quota code not call tty layer with dqptr_sem held udf: Init/maintain file entry checkpoint field ext3: Update ctime in ext3_splice_branch() only when needed ext3: Don't call dquot_free_block() if we don't update anything udf: Remove unnecessary OOM messages
