Merge tag 'ext4_for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tytso/ext4
Pull ext4 updates from Ted Ts'o:
- Add support for online resizing of file systems with bigalloc
- Fix a two data corruption bugs involving DAX, as well as a corruption
bug after a crash during a racing fallocate and delayed allocation.
- Finally, a number of cleanups and optimizations.
