Hello,
This series updates the kernel implementation of CRUSH with a couple of
fixes and a new chooseleaf_vary_r tunable (all ported from ceph.git).
TUNABLES3 feature bit is shared with PRIMARY_AFFINITY, which will also
be posted in a couple of days in order to get everything into 3.15.
Thanks,
Ilya
