2025-05-28f2fs: introduce is_{meta,node}_folioChao Yu
Just cleanup, no changes. Signed-off-by: Chao Yu <chao@kernel.org> Signed-off-by: Jaegeuk Kim <jaegeuk@kernel.org>
2025-05-27f2fs: introduce FAULT_VMALLOCChao Yu
Introduce a new fault type FAULT_VMALLOC to simulate no memory error in f2fs_vmalloc(). Signed-off-by: Chao Yu <chao@kernel.org> Signed-off-by: Jaegeuk Kim <jaegeuk@kernel.org>
2025-05-27f2fs: use vmalloc instead of kvmalloc in .init_{,de}compress_ctxChao Yu
.init_{,de}compress_ctx uses kvmalloc() to alloc memory, it will try to allocate physically continuous page first, it may cause more memory allocation pressure, let's use vmalloc instead to mitigate it. [Test] cd /data/local/tmp touch file f2fs_io setflags compression file f2fs_io getflags file for i in $(seq 1 10); do sync; echo 3 > /proc/sys/vm/drop_caches;\ time f2fs_io write 512 0 4096 zero osync file; truncate -s 0 file;\ done [Result] Before After Delta 21.243 21.694 -2.12% For compression, we recommend to use ioctl to compress file data in background for workaround. For decompression, only zstd will be affected. Signed-off-by: Chao Yu <chao@kernel.org> Signed-off-by: Jaegeuk Kim <jaegeuk@kernel.org>
2025-05-27f2fs: remove unused sbi argument from checksum functionsEric Biggers
Since __f2fs_crc32() now calls crc32() directly, it no longer uses its sbi argument. Remove that, and simplify its callers accordingly. Signed-off-by: Eric Biggers <ebiggers@google.com> Reviewed-by: Chao Yu <chao@kernel.org> Signed-off-by: Jaegeuk Kim <jaegeuk@kernel.org>
2025-05-06f2fs: support FAULT_TIMEOUTChao Yu
Support to inject a timeout fault into function, currently it only support to inject timeout to commit_atomic_write flow to reproduce inconsistent bug, like the bug fixed by commit f098aeba04c9 ("f2fs: fix to avoid atomicity corruption of atomic file"). By default, the new type fault will inject 1000ms timeout, and the timeout process can be interrupted by SIGKILL.

2025-05-06f2fs: handle error cases of memory donationDaeho Jeong
In cases of removing memory donation, we need to handle some error cases like ENOENT and EACCES (indicating the range already has been donated). Signed-off-by: Daeho Jeong <daehojeong@google.com> Reviewed-by: Chao Yu <chao@kernel.org> Signed-off-by: Jaegeuk Kim <jaegeuk@kernel.org>
2025-04-28f2fs: zone: fix to calculate first_zoned_segno correctlyChao Yu
A zoned device can has both conventional zones and sequential zones, so we should not treat first segment of zoned device as first_zoned_segno, instead, we need to check zone type for each zone during traversing zoned device to find first_zoned_segno. Otherwise, for below case, first_zoned_segno will be 0, which could be wrong. create_null_blk 512 2 1024 1024 mkfs.f2fs -m /dev/nullb0 Testcase: export SCRIPTS_PATH=/share/git/scripts test multiple devices w/ zoned device for ((i=0;i<8;i++)) do { zonesize=$((2<<$i)) conzone=$((4096/$zonesize)) seqzone=$((4096/$zonesize)) $SCRIPTS_PATH/nullblk_create.sh 512 $zonesize $conzone $seqzone mkfs.f2fs -f -m /dev/vdb -c /dev/nullb0 mount /dev/vdb /mnt/f2fs touch /mnt/f2fs/file f2fs_io pinfile set /mnt/f2fs/file $((8589934592*2)) stat /mnt/f2fs/file df cat /proc/fs/f2fs/vdb/segment_info umount /mnt/f2fs $SCRIPTS_PATH/nullblk_remove.sh 0 } done test single zoned device for ((i=0;i<8;i++)) do { zonesize=$((2<<$i)) conzone=$((4096/$zonesize)) seqzone=$((4096/$zonesize)) $SCRIPTS_PATH/nullblk_create.sh 512 $zonesize $conzone $seqzone mkfs.f2fs -f -m /dev/nullb0 mount /dev/nullb0 /mnt/f2fs touch /mnt/f2fs/file f2fs_io pinfile set /mnt/f2fs/file $((8589934592*2)) stat /mnt/f2fs/file df cat /proc/fs/f2fs/nullb0/segment_info umount /mnt/f2fs $SCRIPTS_PATH/nullblk_remove.sh 0 } done Fixes: 9703d69d9d15 ("f2fs: support file pinning for zoned devices") Cc: Daeho Jeong <daehojeong@google.com> Signed-off-by: Chao Yu <chao@kernel.org> Signed-off-by: Jaegeuk Kim <jaegeuk@kernel.org>
