From ec5a3b4b507efca903d848518dcf2ebf7b04b466 Mon Sep 17 00:00:00 2001 From: David Howells Date: Thu, 10 May 2018 14:22:38 +0100 Subject: [PATCH] afs: Fix server rotation's handling of fileserver probe failure The server rotation algorithm just gives up if it fails to probe a fileserver. Fix this by rotating to the next fileserver instead.
