Subject: [BUG] NULL deref in jbd2_journal_grab_journal_head
Dear jbd2 maintainers,
I observed the below BUG a couple of seconds after resuming from ram. I
include all the fallout, in hope that it may be helpful.
I am using kernel 3.2.1.
Please let me know what other details I could provide.
With kind regards,
Wouter Koolen
