[PATCH v2 0/1] qemu-iotests: One more fuse fix

[Eric Farman]

Hi,

After learning about Denis' series of fuse fixes, there's still
one test that doesn't run on my system. The attached is a fix that
builds upon their changes to fix test 108 as well.

v1: https://lore.kernel.org/r/20260725125651.3896151-1-farman@linux.ibm.com/
v1->v2:
 - [KW] Rebase on https://lore.kernel.org/r/20260715103451.1930909-1-den@openvz.org/
   and drop two of the (now superfluous) patches

Eric Farman (1):
  iotests/108: skip test if cannot access /dev/fuse

[PATCH v2 1/1] iotests/108: skip test if cannot access /dev/fuse

[Eric Farman]

This test might fail if the user is not root (or sudo'd):

  fusermount3: failed to open .../scratch/qcow2-file-108/fuse-export: Permission denied

A check exists to try to cover for this, but there are
two potential error messages that signal this case
(per the comment block associated with the check) and
only a skip for one of them.

Update the common fuse check to include this message,
and update test 108 to utilize it.

Fixes: 9ffd6d646d ("iotests/108: Test new refcount rebuild algorithm")
