Subject: [PATCH AUTOSEL 5.2 46/94] SUNRPC: Handle connection breakages correctly in call_status()

From: Trond Myklebust <trond.myklebust@...merspace.com>

[ Upstream commit c82e5472c9980e0e483f4b689044150eefaca408 ]

If the connection breaks while we're waiting for a reply from the
server, then we want to immediately try to reconnect.

Fixes: ec6017d90359 ("SUNRPC fix regression in umount of a secure mount")
