- What I did
Change
usesMetacopyinoverlay2'scheck.goto return false/no error on aENOTSUPin lgetxattr(2).- How to verify it
By reading kernel documentation, more or less. ENOTSUP does not indicate that something went wrong, but that either the xattr in question, or xattr as a whole, are not supported by the filesystem.
- Description for the changelog
overlay2storage driver failing in a check for metacopy status instead of backing FS compatibility on incompatible backing filesystems.- A picture of a cute animal (not mandatory but encouraged)
