If anyone has any objections, please let me know. ------------------ From: Alex Elder (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.
