To be entirely complete, I also upgraded the kernel RBD client and
since the leak happened while scrubbing the RBD pool, maybe the client
behavior makes a difference..

Previously they were running kernel 3.6.8, they're now running 3.6.11
with all the ceph related patch from 3.8 backported ( ~ 150 patches ).

Cheers,
