4.16-stable review patch. If anyone has any objections, please let me know.
------------------
From: David Howells <dhowells@xxxxxxxxxx>
[ Upstream commit ec5a3b4b507efca903d848518dcf2ebf7b04b466 ]
The server rotation algorithm just gives up if it fails to probe a
fileserver. Fix this by rotating to the next fileserver instead.
Fixes: d2ddc776a458 ("afs: Overhaul volume and server record caching and fileserver rotation")
