Pull ext4 bug fixes from Ted Ts'o: "The following are all bug fixes and regressions. The most notable are the ones which cause problems for ext4 on RAID --- a performance problem when mounting very large filesystems, and a kernel OOPS when doing an rm -rf on large directory hierarchies on fast devices." * tag 'ext4_for_linus_stable' of git://git.kernel.org/pub/scm/linux/kernel/git/tytso/ext4: ext4: fix kernel BUG on large-scale rm -rf commands ext4: fix long mount times on very big file systems ext4: don't call ext4_error while block group is locked ext4: avoid kmemcheck complaint from reading uninitialized memory ext4: make sure the journal sb is written in ext4_clear_journal_err()
