We have +AD4 an exported interface that does direct dispatch, with DM being the sole +AD4 user of it. Change that to do bypass insert always instead of attempting +AD4 direct dispatch. This fixes a deadlock that can happen on DM. +AD4 Additionally, it gets rid of any exported user of direct dispatch, and +AD4 enables DM to drop any BUSY handling from using the interface. +AD4 +AD4 Please pull+ACE +AD4 +AD4 +AD4 git://git.kernel.dk/linux-block.git tags/for-linus-20181206 Hi Jens, Which branch does that tag correspond to? Even after having run git fetch --tags I can't find that tag in your repository. Additionally, the patch on your for-linus branch is missing the +ACI-Cc: stable+ACI and +ACI-Reported-by:+ACI tags that you had promised to add. Did I look at the wrong branch? Thanks, Bart.
