Merge tag 'ext4_for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tytso/ext4
Pull ext4 bug fixes from Ted Ts'o: "Various bug fixes for ext4. The most important is a fix for the new extent cache's slab shrinker which can cause significant, user-visible pauses when the system is under memory pressure." * tag 'ext4_for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tytso/ext4: ext4: enable quotas before orphan cleanup ext4: don't allow quota mount options when quota feature enabled ext4: fix a warning from sparse check for ext4_dir_llseek ext4: convert number of blocks to clusters properly ext4: fix possible memory leak in ext4_remount() jbd2: fix ERR_PTR dereference in jbd2__journal_start ext4: use percpu counter for extent cache count ext4: optimize ext4_es_shrink()
