  ceph: don't encode inode pathes into reconnect message (2018-12-26 16:08:36 +0100)

----------------------------------------------------------------
A fairly quiet round: a couple of messenger performance improvements
from myself and a few cap handling fixes from Zheng.

----------------------------------------------------------------
Chengguang Xu (1):
      ceph: remove redundant assignment

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()

Yan, Zheng (6):
      ceph: cleanup splice_dentry()
      ceph: don't update importing cap's mseq when handing cap export
      ceph: don't request excl caps when mount is readonly
      ceph: skip updating 'wanted' caps if caps are already issued
      ceph: update wanted caps after resuming stale session
      ceph: don't encode inode pathes into reconnect message
