Hi,

unfreeze function, thaw_super(), sometimes hangs up if flush kernel

This test runs freeze/unfreeze under heavy load. If the problem is
reproduced, this test will hang up...

This is effectively a duplicate of test 068, which is currently
described as an XFS only test. It is actually generic now that
xfs_freeze works on other filesytsems, so please update 068
appropriately rather that introducing a new test.

Cheers,

Dave
