afs: Need to clear responded flag in addr cursor
In afs_select_fileserver(), we need to clear the ->responded flag in the address list when reusing it. We should also clear it in afs_select_current_fileserver(). To this end, just memset() the object before initialising it. Fixes: d2ddc776a458 ("afs: Overhaul volume and server record caching and fileserver rotation") Signed-off-by: David Howells <dhowells@redhat.com> cc: stable@vger.kernel.org
