Subject: [PATCH 0/4] ext4: Fix deadlock during page writeback
Date: Thu, 16 Jun 2016 12:42:12 +0200	[thread overview]
Message-ID: <1466073736-30447-1-git-send-email-jack@suse.cz> (raw)


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.
