* ceph_test_rados: do not let rollback race with snap deletewip-6254-modelSage Weil2013-10-032-3/+10

That means that the mds conversion from tmap -> omap won't be able to use this because any existing cluster has tmap objects without the USES_TMAP flag set. And we don't want to unconditionally try a tmap->omap conversion on omap operations because there are lots of existing librados users out there that will be negatively impacted by this. Instead, the MDS will need to handle this conversion on the client side by reading either tmap or omap objects and explicitly rewriting the content with omap (while truncating the tmap data away). The auto-conversion function was added in v0.44. Signed-off-by: Sage Weil <sage@inktank.com>
