They can be easily fixed with fsck_hfs from hfsprogs though. > (3) Let me prepare environment and start to run xfstests for HFS/HFS+ (to check > the current status). I suggest a Debian VM for that as it has hfsprogs which allows creating both HFS and HFS+ filesystems. It's also easily possible to test on PowerPC inside QEMU if necessary. > (4) Which use-cases do we need to consider for regular testing? Definitely testing both legacy HFS and HFS+ with creating new filesystems, writing and reading random files from it as well as running fsck on these. I'm not a Linux kernel filesystem expert, so I don't know what the recommend tests for CI are, but I suggest everything that is commonly used, both with HFS and HFS+. > Anything else? What am I missing? No, I think that should get us going for the time being. Adrian -- .''`.
