| Subject: afs: Fix server rotation's handling of fileserver probe failure |
| |
| From: David Howells <dhowells@redhat.com> |
| |
| [ 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") |
