Merge tag 'rxrpc-fixes-20190809' of git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs
David Howells says:
====================
Here's a couple of fixes for rxrpc:
(1) Fix refcounting of the local endpoint.
(2) Don't calculate or report packet skew information. This has been
obsolete since AFS 3.1 and so is a waste of resources.
====================
