Subject[PATCH 4.9 051/101] libceph: factor out __prepare_write_connect()
Date
4.9-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Ilya Dryomov <idryomov@gmail.com>

commit c0f56b483aa09c99bfe97409a43ad786f33b8a5a upstream.

Will be used for sending ceph_msg_connect with an updated authorizer,
after the server challenges the initial authorizer.
