Hi Andreas,

I see your point, and sure, the maintainers of xfstests can improve the 
tests to make them check whether the options are supported for gfs2 as
they do with other some other options.

Still, if you look at the man page for "mount(8)" under "Mount options 
for affs" you see:

"grpquota|noquota|quota|usrquota
These options are accepted but ignored.  (However, quota utilities may 
react to such strings in /etc/fstab.)"

If you look at "Mount options for jfs" you similarly see:

"noquota|quota|usrquota|grpquota
These options are accepted but ignored."

So if affs and jfs can ignore these mount options, why can't gfs2?
Are we planning to support them ever?
