Subject[PATCH AUTOSEL 5.4 08/26] fs: dlm: cancel work sync othercon
Date
From: Alexander Aring <aahringo@redhat.com>

[ Upstream commit c6aa00e3d20c2767ba3f57b64eb862572b9744b3 ]

These rx tx flags arguments are for signaling close_connection() from
which worker they are called. Obviously the receive worker cannot cancel
itself and vice versa for swork. For the othercon the receive worker
should only be used, however to avoid deadlocks we should pass the same
flags as the original close_connection() was called.
