ceph: avoid null deref in osd request error path If we interrupt an osd request, we call __cancel_request, but it wasn't verifying that req->r_osd was non-NULL before dereferencing it. This could cause a crash if osds were flapping and we aborted a request on said osd. Reported-by: Henry C Chang <henry_c_chang@tcloudcomputing.com> Signed-off-by: Sage Weil <sage@newdream.net>
