David Howells says:
====================
rxrpc: Fixes
This set of patches contains a bunch of fixes:
(1) Fix use of kunmap() after change from kunmap_atomic() within AFS.
(2) Don't use of ERR_PTR() with an always zero value.
(3) Check the right error when using ip6_route_output().
(4) Be consistent about whether call->operation_ID is BE or CPU-E within
AFS.
