Merge tag 'rxrpc-next-20171018' of git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs
David Howells says:
====================
rxrpc: Add bits for kernel services
Here are some patches that add a few things for kernel services to use:
(1) Allow service upgrade to be requested and allow the resultant actual
service ID to be obtained.
(2) Allow the RTT time of a call to be obtained.
(3) Allow a kernel service to find out if a call is still alive on a
server between transmitting a request and getting the reply.
(4) Allow data transmission to ignore signals if transmission progress is
being made in reasonable time. This is also usable by userspace by
passing MSG_WAITALL to sendmsg()[*].
[*] I'm not sure this is the right interface for this or whether a sockopt
should be used instead.
