From: Alex Elder Date: Thu, 6 Dec 2012 13:22:04 +0000 (-0600) Subject: libceph: init osd->o_node in create_osd() X-Git-Tag: upstream/snapshot3+hdmi~5940^2~8 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=f407731d12214e7686819018f3a1e9d7b6f83a02;p=platform%2Fadaptation%2Frenesas_rcar%2Frenesas_kernel.git libceph: init osd->o_node in create_osd() 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.
