Hi Jaegeuk Kim, Chao Yu,

In Debian the following regression was reported after a Dhya updated
Package: src:linux
Version: 6.1.76-1
Severity: critical
Justification: breaks the whole system
Dear Maintainer,
After upgrade to linux-image-6.1.0-18-amd64 6.1.76-1 F2FS filesystem
kernel: F2FS-fs (nvme0n1p6): invalid zstd compress level: 6
There was recently an f2fs patch to the 6.1 kernel tree which might be
related: https://www.spinics.net/lists/stable-commits/msg329957.html
sudo mount -o remount,rw,relatime,lazytime,background_gc=on,discard,no_heap,user_xattr,inline_xattr,acl,inline_data,inline_dentry,extent_cache,mode=adaptive,active_logs=6,alloc_mode=default,checkpoint_merge,fsync_mode=posix,compress_algorithm=lz4,compress_log_size=2,compress_mode=fs,atgc,discard_unit=block,memory=normal /dev/nvme0n1p6 /
under the running bad 6.1.0-18-amd64 kernel, then editing
GRUB_DEFAULT="Advanced options for Debian GNU/Linux>Debian GNU/Linux, with Linux 6.1.0-17-amd64"
and running 'update-grub' and rebooting to boot the 6.1.0-17-amd64
kernel.
The issue is easily reproducible by:

# dd if=/dev/zero of=test.img count=100 bs=1M
# mkfs.f2fs -f -O compression,extra_attr ./test.img
# mount -t f2fs -o compress_algorithm=zstd:6,compress_chksum,atgc,gc_merge,lazytime ./test.img /mnt

resulting in

[ 60.789982] F2FS-fs (loop0): invalid zstd compress level: 6

Hi Salvatore,
[PATCH 6.1] f2fs: add helper to check compression level
Confirmed that this fixes the reported issue as it was reported to us
in Debian in https://bugs.debian.org/1063422 . Thanks a lot!
(note just tested with the first commit as it landed in 6.1.78 to
confirm the immediate regression).
