[PATCH v3 0/4] iotests fixes

Hi Kevin, Hanna,

Here is a third version of iotests fixes from our s390x systems.
They aren't related, just came up walking through the failures.

In fact, only patch 4 has existed in the previous versions of this "series",
as it remains stubborn for me (hence me putting it at the end). This time,
I added a check against the qemu-storage-daemon to try to do a mount against
a null device (similar to the test_fuse_support() routine in fuse-mmap-shared),
to bail out of the test earlier than failing on the "real" command later on.

I look forward to your feedback...

v1: https://lore.kernel.org/r/[email protected]/
v2: https://lore.kernel.org/r/[email protected]/
v2->v3:
 - [EF] Add two fixes for NBD tests, and one (new) fix for another FUSE test
 - [HC] Rework the fix to 108, and perform a dummy mount to see if fuse works

Eric Farman (4):
  iotests/nbd-in-qcow2-chain: use default machine
  iotests/nbd-tls-iothread: skip on non-x86 hardware
  iotests/fuse-truncate: skip if FUSE is not usable
  iotests/108: skip if fuse is unsuable
