Hello,

This series fixes the suboptimal behavior around ceph_tcp_sendpage()
that I noticed while tracking down skb_can_coalesce() vs usercopy bug.

Thanks,

                Ilya


Ilya Dryomov (4):
  libceph: drop last_piece logic from write_partial_message_data()
  libceph: use sock_no_sendpage() as a fallback in ceph_tcp_sendpage()
  libceph: use MSG_SENDPAGE_NOTLAST with ceph_tcp_sendpage()
  libceph: switch more to bool in ceph_tcp_sendmsg()
