From: Darrick J. Wong <darrick.wong@oracle.com>

In XFS, mounting with quota always require a writable device.  If the
block device is read only, the mount fails, which fails this test.
Since this is expected, work around this.

This touch expects a failure message, but with this change applied, test
still failed when testing with "-o usrquota,grpquota,prjquota" mount
options as

Hmm, what kernel is this on?  I've never seen this problem, but maybe I
just have too many patches everywhere. :/

I cannot remember.. But I think the problem here is that, ro mount with
quota failed but we amended & hid the failure by filter_ro_mount, then
the 'touch' expected a ro-mounted fs, but it actually created a new file
on rootfs without hitting the EROFS error.

ARrrggh, I forgot that most people run fstests with a rw rootfs. :/

Ok that gives me something to go on.
