Merge tag 'rxrpc-fixes-20171129' of git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs
David Howells says: ==================== rxrpc: Fixes Here are three patches for AF_RXRPC. One removes some whitespace, one fixes terminal ACK generation and the third makes a couple of places actually use the timeout value just determined rather than ignoring it. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
