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" * tag 'f2fs-for-4.19' of git://git.kernel.org/pub/scm/linux/kernel/git/jaegeuk/f2fs: (89 commits) f2fs: readahead encrypted block during GC f2fs: avoid fi->i_gc_rwsem[WRITE] lock in f2fs_gc f2fs: fix performance issue observed with multi-thread sequential read f2fs: fix to skip verifying block address for non-regular inode f2fs: rework fault injection handling to avoid a warning f2fs: support fault_type mount option f2fs: fix to return success when trimming meta area f2fs: fix use-after-free of dicard command entry f2fs: support discard submission error injection f2fs: split discard command in prior to block layer f2fs: wake up gc thread immediately when gc_urgent is set f2fs: fix incorrect range->len in f2fs_trim_fs() f2fs: refresh recent accessed nat entry in lru list f2fs: fix avoid race between truncate and background GC f2fs: avoid race between zero_range and background GC f2fs: fix to do sanity check with block address in main area v2 f2fs: fix to do sanity check with inline flags f2fs: fix to reset i_gc_failures correctly f2fs: fix invalid memory access f2fs: fix to avoid broken of dnode block list ...
