Date: Tue, 15 Jan 2013 14:45:09 -0800 From: Greg Kroah-Hartman <gregkh@...uxfoundation.org> To: linux-kernel@...r.kernel.org, stable@...r.kernel.org Cc: Greg Kroah-Hartman <gregkh@...uxfoundation.org>, alan@...rguk.ukuu.org.uk, Alex Elder <elder@...tank.com>, Sage Weil <sage@...tank.com> Subject: [ 144/171] libceph: init osd->o_node in create_osd() 3.4-stable review patch. If anyone has any objections, please let me know. ------------------ From: Alex Elder <elder@...tank.com> 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.
