Description
Looking at recent review test runs to see where the time is being spent, I see that conf-sanity.sh test_53a and test_53b are sometimes taking far too long to run - over 800s and 1000s respectively, sometimes twice that. They should be able to complete in a few seconds, but the remount in the middle of the test seems to take the longest time. Given that these tests run in our test environment about 20x per day, this could be wasting 10h or more of testing time each day.
Some investigation needs to be done to see why these tests are taking so long to run. Is it that mount and/or unmount is very slow? If so, why? Simply skipping these tests for SLOW=no is not a valid solution, since slow mounting/unmounting affects all of our users and wastes even more time for every test that is run, but it is less visible when done at the start of a test run instead of in the middle.
