Merge tag 'f2fs-for-5.4' of git://git.kernel.org/pub/scm/linux/kernel/git/jaegeuk/f2fs
Pull f2fs updates from Jaegeuk Kim:
"In this round, we introduced casefolding support in f2fs, and fixed
various bugs in individual features such as IO alignment,
checkpoint=disable, quota, and swapfile.
Enhancement:
- support casefolding w/ enhancement in ext4
- support fiemap for directory
- support FS_IO_GET|SET_FSLABEL
Bug fix:
- fix IO stuck during checkpoint=disable
- avoid infinite GC loop
- fix panic/overflow related to IO alignment feature
- fix livelock in swap file
- fix discard command leak
- disallow dio for atomic_write"
