Pull ext4 fixes from Ted Ts'o: "Some miscellaneous ext4 fixes for 4.18; one fix is for a regression introduced in 4.18-rc4. Sorry for the late-breaking pull. I was originally going to wait for the next merge window, but Eric Whitney found a regression introduced in 4.18-rc4, so I decided to push out the regression plus the other fixes now. (The other commits have been baking in linux-next since early July)" * tag 'ext4_for_linus_stable' of git://git.kernel.org/pub/scm/linux/kernel/git/tytso/ext4: ext4: fix check to prevent initializing reserved inodes ext4: check for allocation block validity with block group locked ext4: fix inline data updates with checksums enabled ext4: clear mmp sequence number when remounting read-only ext4: fix false negatives *and* false positives in ext4_check_descriptors()
