From 3120c170ef35c1a9be137535e44c7e237e33b78e Mon Sep 17 00:00:00 2001 From: David Howells Date: Wed, 27 May 2020 16:44:02 +0100 Subject: afs: Fix handling of CB.ProbeUuid cache manager op The AFS filesystem driver is handling the CB.ProbeUuid request incorrectly. The UUID presented in the request is that of the cache manager, not the fileserver, so afs_deliver_cb_probe_uuid() shouldn't be using that UUID to look up the server. Fix this by looking up the server by address instead.
