Hi, unfreeze function, thaw_super(), sometimes hangs up if flush kernel thread does writeback to the same filesystem concurrently. (the problem is reported at http://marc.info/?l=linux-ext4&m=132339590004560&w=2) This test runs freeze/unfreeze under heavy load. If the problem is reproduced, this test will hang up...
