[PATCH 075/270] libceph: kill bad_proto ceph connection op

[Herton Ronaldo Krzesinski]

3.5.7u1 -stable review patch.  If anyone has any objections, please let me know.

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

From: Alex Elder <elder at inktank.com>

commit 6384bb8b8e88a9c6bf2ae0d9517c2c0199177c34 upstream.

No code sets a bad_proto method in its ceph connection operations
vector, so just get rid of it.
