f2fs: compress: fix to check zstd compress level correctly in mount o…
…ption [ Upstream commit e39602da752cd1d0462e3fa04074146f6f2803f6 ] f2fs only support to config zstd compress level w/ a positive number due to layout design, but since commit e0c1b49 ("lib: zstd: Upgrade to latest upstream zstd version 1.4.10"), zstd supports negative compress level, so that zstd_min_clevel() may return a negative number, then w/ below mount option, .compress_level can be configed w/ a negative number, which is not allowed to f2fs, let's add check condition to avoid it. mount -o compress_algorithm=zstd:4294967295 /dev/sdx /mnt/f2fs Fixes: 00e120b ("f2fs: assign default compression level") Signed-off-by: Chao Yu <chao@kernel.org> Signed-off-by: Jaegeuk Kim <jaegeuk@kernel.org> Signed-off-by: Sasha Levin <sashal@kernel.org>
