lots of mounts/remounts of the test file system?

[Christoph Hellwig <hch@infradead.org>]

Hi all,

I've been hacking on some (XFS) code that in this state of development
requires a mount options to be passed for every mount, and I noticed
that even when running without a SCRATCH_DEV I have to add the required
option to MOUNT_OPTIONS and not just TEST_FS_MOUNT_OPTS, which is a bit
odd.  I've been trying to track it down and despite multiple attempts
failed to find my way through the bash code for it.

But what is even more odd is that when running just a single test (e.g.
generic/001), the test fs gets mounted four times, with the second
and fourth time failing to apply the mount options.
