Cover letter [PATCH 0/5] libceph: page mapping in the messenger
This series fixes up some things in the messenger code related to how it uses pages. A new ceph_tcp_sendpage() helper is created to match the existing ceph_tcp_sendmsg() interface, and it is used rather than the sendmsg interface when sending zeroes over the wire for a revoked message. The helper is also used for sending message data. Also, the address mapping to the zero page gets eliminated, thereby making the zero page get treated no differently than any other page when it is the source of a send operation. Finally there is a little code cleanup in the message sending code.
