PM / Sleep: JBD and JBD2 missing set_freezable()
With the latest and greatest changes to the freezer, I started seeing panics that were caused by jbd2 running post-process freezing and hitting the canary BUG_ON for non-TuxOnIce I/O submission. I've traced this back to a lack of set_freezable calls in both jbd and jbd2. Since they're clearly meant to be frozen (there are tests for freezing()), I submit the following patch to add the missing calls.
