Merge tag 'afs-fixes-20190413' of git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs

Pull AFS fixes from David Howells:

 - Stop using the deprecated get_seconds().

 - Don't make tracepoint strings const as the section they go in isn't
   read-only.

 - Differentiate failure due to unmarshalling from other failure cases.
   We shouldn't abort with RXGEN_CC/SS_UNMARSHAL if it's not due to
   unmarshalling.

 - Add a missing unlock_page().

 - Fix the interaction between receiving a notification from a server
   that it has invalidated all outstanding callback promises and a
   client call that we're in the middle of making that will get a new
   promise.
