Subject: libceph: init osd->o_node in create_osd()
From: Alex Elder <[email protected]>
(cherry picked from commit f407731d12214e7686819018f3a1e9d7b6f83a02)
The red-black node node in the ceph osd structure is not initialized
in create_osd(). Because this node can be the subject of a
RB_EMPTY_NODE() call later on, we should ensure the node is
initialized properly for that. Add a call to RB_CLEAR_NODE()
initialize it.
