Subject: [PATCH] ksmbd: call ib_drain_qp when disconnected
Date: Sun,  2 Oct 2022 12:01:23 +0900	[thread overview]
Message-ID: <20221002030123.11409-1-linkinjeon@kernel.org> (raw)

When disconnected, call ib_drain_qp to cancel all pending work requests
and prevent ksmbd_conn_handler_loop from waiting for a long time
for those work requests to compelete.
