Subject: [PATCH 0/4] ext4: Fix deadlock during page writeback

Hello,

the first patch in the series fixes the deadlock during page writeback
spotted by Eryu. Other three patches somewhat improve the lockdep
instrumentations of transactions in JBD2. Originally I though we would
be able to catch the writeback deadlock with them but sadly that is not
the case as page locks / page writeback bits are not tracked by lockdep.
But still the result looks nicer and has more coverage so I think it is
worth it.
