Merge tag 'rxrpc-rewrite-20161013' of git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs
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. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
