Revision e1ede312f17e96a9c5cda9aaa1cdcf442c1a5da8 authored by Chuck Lever on 09 April 2019, 21:04:09 UTC, committed by Trond Myklebust on 11 April 2019, 19:23:48 UTC 
xprtrdma: Fix helper that drains the transport
 
We want to drain only the RQ first. Otherwise the transport can
deadlock on ->close if there are outstanding Send completions.

Fixes: 6d2d0ee27c7a ("xprtrdma: Replace rpcrdma_receive_wq ... ")
