--- Comment #1 from Chao Yu (c...@kernel.org) ---
Hi, thanks for the report.
What's you mkfs/mount option?
I've no idea whether this is a f2fs bug or not, as you said device can be
trusted, so almostly it should be a software bug.
One case I can image could be that apps bypassing filesystem to write data via
LBA directly, then data can be corrupted.
If possible, could you please help to add below three patches to recompile the
kernel
https://lore.kernel.org/linux-f2fs-devel/20200628122940.29665-1-yuch...@huawei.com/T/#t
[f2fs-dev] [PATCH 1/3] f2fs: fix wrong return value of f2fs_bmap_compress()
[f2fs-dev] [PATCH 2/3] f2fs: support to trace f2fs_bmap()
[f2fs-dev] [PATCH 3/3] f2fs: support to trace f2fs_fiemap()
Then, use below commands to see whether there is apps are lookuping LBA:
echo 1 > /sys/kernel/debug/tracing/events/f2fs/f2fs_bmap/enable
echo 1 > /sys/kernel/debug/tracing/events/f2fs/f2fs_fiemap/enable
cat /sys/kernel/debug/tracing/trace_pipe |grep f2fs
