Subject: [GIT PULL] Follow up block fix
Date: Thu, 6 Dec 2018 16:59:04 -0700 [thread overview]
Message-ID: <fd37a010-d44e-dab7-4e39-059a339091eb@kernel.dk> (raw)
Hi Linus,
Just a single followup fix to the corruption fix from yesterday. We have
an exported interface that does direct dispatch, with DM being the sole
user of it. Change that to do bypass insert always instead of attempting
direct dispatch. This fixes a deadlock that can happen on DM.
Additionally, it gets rid of any exported user of direct dispatch, and
enables DM to drop any BUSY handling from using the interface.
Please pull!
