Subject: [PATCH 20/20] tests: Use wait_for_dev_to_ functions
Recent changes to udev have made some long-standing problems appear more
frequently. udev executes various actions when changes are made to
devices. Sometimes this can result in device nodes not appearing
immediately. Other times it can result in EBUSY being returned. This
patch only addresses devices that are slow to appear/disappear.
It is best to use the wait_for_dev_to_appear_ and
wait_for_dev_to_disappear_ functions than to test for existance. These
will loop and wait for up to 2 seconds for it to appear.
This also changes t9041 to fail if mkfs doesn't work since using skip
here may hide cases when the device node doesn't appear.
(cherry picked from commit 1dc13965e1108ab513662450e0171c3ea3af3bd1)
