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. Enhancement: - 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 -----BEGIN PGP SIGNATURE----- iQIzBAABCAAdFiEE00UqedjCtOrGVvQiQBSofoJIUNIFAlt82U4ACgkQQBSofoJI UNJTLQ/+PhewnNa5tDfUgWdFnUFz3h9/NcC677l0OplOOUNxA8iSa1xamlKf/nf9 sB5ey0I7oBF8zQGxfndhHQfi6fpfUcNMr14hm+TS/3+d54xLJmiVShD5fjNSV2vB Ur0xoozuQDwYF1e3QKdBQjFqaCf78VheTr3aWxyv22/Sg+PYylZJ2K8rHTB7mGPU UG0aRnKrP3FPRjL7Q3m0Vm6b6eZ5uNdNrFfjgn/8yuQQ9V197K8vwSbPAsR5/pOh miCQXyM708NgEYJRWkWmC/rDSQdU0/h/mGnJWrBrbceW62QefGOgd2jcVfmthHJa ZXpj+BEG5bYpCCxGxF6N+u0e28OKonCwO/uvL8YAd5icN7yXtsKzoF1CCuXxOYf1 9K5SMylCTSyrs/+LV8CJoT2ya8w0l0w+R/txUYn8UT+4AgqU+chS2kJeXqw9tcHB WLFs/rnAyofWCI/8frVBmJY+zA1ZZvTqs/lmVYrtJUkiOcMTq34WICBUAEFKV452 BM5dcu21bSIkapYispEt4Rr7o4P4HHMQ+N1i2yUZMFCz5T0RyzdybeS5THk2yVzd L0kxfYU+zHigNX51ez8+Z7DyDLDBp6jkD0e66x73bUK9TGPH+ZbnAL6gwLikmD3M +VxYl5nyW/3bxx1HdfK1Xwd4/wYMNBmdtn5NC50oZ+jpB0h8YCE= =zgbL -----END PGP SIGNATURE----- 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.
