Merge tag 'f2fs-for-4.19' of git://git.kernel.org/pub/scm/linux/kernel/git/jaegeuk/f2fs
Pull f2fs updates from Jaegeuk Kim:
"In this round, we've tuned f2fs to improve general performance by
serializing block allocation and enhancing discard flows like fstrim
which avoids user IO contention. And we've added fsync_mode=nobarrier
which gives an option to user where it skips issuing cache_flush
commands to underlying flash storage. And there are many bug fixes
related to fuzzed images, revoked atomic writes, quota ops, and minor
direct IO.
Enhancements:
- add fsync_mode=nobarrier which bypasses cache_flush command
- enhance the discarding flow which avoids user IOs and issues in
LBA order
- readahead some encrypted blocks during GC
- enable in-memory inode checksum to verify the blocks if
F2FS_CHECK_FS is set
- enhance nat_bits behavior
- set -o discard by default
- set REQ_RAHEAD to bio in ->readpages
Bug fixes:
- fix a corner case to corrupt atomic_writes revoking flow
- revisit i_gc_rwsem to fix race conditions
- fix some dio behaviors captured by xfstests
- correct handling errors given by quota-related failures
- add many sanity check flows to avoid fuzz test failures
- add more error number propagation to their callers
- fix several corner cases to continue fault injection w/ shutdown
loop"
