[btrfs-progs PATCHv3 0/3] tests: do not fail if dm-thin is missing

[Marcos Paulo de Souza <marcos.souza.org@gmail.com>]

From: Marcos Paulo de Souza <mpdesouza@suse.com>

This is the third version, which basically removes the last patch, as suggested
by David, and reworks the first one, by keeping the $SUDO_HELPER call and adding
the setup_root_helper function call before calling $SUDO_HELPER. The tests 005
and 017 are now skipped when triggered in a kernel without dm-thin.

Please review.

Original message:

these patchset is trying to fix the issue 192[1] by checking if dm-thin exists,
and if it's not available, skip the test. In the last patch, the same is done
for dmsetup. Feel free to ignore the last patch if you think we should stop the
tests if dmsetup isn't available.

Thanks!
