Hello,
This is on top of wip-tunables3, which I posted a week ago and brings
the support for the new osdmap encoding (OSDMAP_ENC feature bit),
primary_temp and primary affinity (PRIMARY_AFFINITY feature bit) to the
kernel client, along with some cleanups. PRIMARY_AFFINITY feature bit
is shared with CRUSH_TUNABLES3, so wip-primary branch contains both
this series and chooseleaf_vary_r stuff.
- 01-16/33, 24-25/33 common ground + misc fixes and cleanups
- 17-23/33 new osdmap encoding + infrastructure
- 26-28/33, 32/33 refactor pg -> (osd set, primary) code paths
- 29-31/33, 33/33 primary_temp and primary affinity logic
Thanks,
Ilya
