Merge tag 'f2fs-for-4.20-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/jaegeuk/f2fs
Pull f2fs updates from Jaegeuk Kim:
"In this round, we've added 1) superblock checksum feature, 2)
implemented new mount option which we can disable/enable checkpoint to
provide atomic updates of entire filesystem, 3) refactored quota
operations to enhance its consistency along with checkpoint, 4) fixed
subtle IO hang conditions and roll-forward recovery flow to resurrect
any fsync'ed inode metadata.
Enhancements:
- add checksum to keep superblock contents more safe
- add checkpoint=disable/enable to support A/B update of entire filesystem
- use plug for readahead IO in readdir
- add more IO counts to avoid block layer hacks
Bug fixes:
- prevent data corruption issue for hardware encryption
- fix IO hang issues when GC is heavily triggered
- add missing up_read in __write_node_page
- recover inode metadata during roll-forward recovery flow
- fix null pointer dereference issue in wrongly configured discard map
There are some more sanity checks and minor bug fixes as well"
