From 9bd11523dc1b9293d1eee2c0b8cfc986a312bbce Mon Sep 17 00:00:00 2001 From: Trond Myklebust Date: Fri, 30 Nov 2018 12:48:47 -0500 Subject: [PATCH] SUNRPC: call_connect_status() must handle tasks that got transmitted If a task failed to get the write lock in the call to xprt_connect(), then it will be queued on xprt->sending. In that case, it is possible for it to get transmitted before the call to call_connect_status(), in which case it needs to be handled by call_transmit_status() instead.
