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 A bugzilla report has been submitted in https://bugzilla.kernel.org/show_bug.cgi?id=218471 #regzbot introduced: v6.1.69..v6.1.76 #regzbot link: https://bugs.debian.org/1063422 #regzbot link: https://bugzilla.kernel.org/show_bug.cgi?id=218471 Regards, Salvatore
