Merge tag 'f2fs-for-5.1' of git://git.kernel.org/pub/scm/linux/kernel/git/jaegeuk/f2fs
Pull f2fs updates from Jaegeuk Kim:
"We've continued mainly to fix bugs in this round, as f2fs has been
shipped in more devices. Especially, we've focused on stabilizing
checkpoint=disable feature, and provided some interfaces for QA.
Enhancements:
- expose FS_NOCOW_FL for pin_file
- run discard jobs at unmount time with timeout
- tune discarding thread to avoid idling which consumes power
- some checking codes to address vulnerabilities
- give random value to i_generation
- shutdown with more flags for QA
Bug fixes:
- clean up stale objects when mount is failed along with
checkpoint=disable
- fix system being stuck due to wrong count by atomic writes
- handle some corrupted disk cases
- fix a deadlock in f2fs_read_inline_dir
We've also added some minor build error fixes and clean-up patches"
