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. * tag 'afs-fixes-20190413' of git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs: afs: Fix in-progess ops to ignore server-level callback invalidation afs: Unlock pages for __pagevec_release() afs: Differentiate abort due to unmarshalling from other errors afs: Avoid section confusion in CM_NAME afs: avoid deprecated get_seconds()
