[PATCHSET] fstests: more random fixes for v2025.11.04

["Darrick J. Wong" <djwong@kernel.org>]

Hi all,

Here's the usual odd fixes for fstests.

If you're going to start using this code, I strongly recommend pulling
from my git trees, which are linked below.

With a bit of luck, this should all go splendidly.
Comments and questions are, as always, welcome.
