Subject: [PATCH 5/9] dlm: WQ_NON_REENTRANT is meaningless and going away

Hello,

Please route this through the subsystem tree.  As written in the
description, this shouldn't make any functional difference and just
prepares for the removal of WQ_NON_REENTRANT which is already noop.

Thanks.

------ 8< -------
dbf2576e37 ("workqueue: make all workqueues non-reentrant") made
WQ_NON_REENTRANT no-op and the flag is going away.  Remove its usages.

This patch doesn't introduce any behavior changes.
