AFS: Correctly translate auth error aborts and don't failover in such cases
Authentication error abort codes should be translated to appropriate Linux error codes, rather than all being translated to EREMOTEIO - which indicates that the server had internal problems. Additionally, a server shouldn't be marked unavailable and the next server tried if an authentication error occurs. This will quickly make all the servers unavailable to the client. Instead the error should be returned straight to the user. Signed-off-by: David Howells <dhowells@redhat.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
