Hello,
This is a v2 of the CEPH_OSD_OP_SETALLOCHINT osd op series.
Incorporated are Sage's and Alex's comments. The rationale and the
basic design is outlined in the "rados io hints" thread on ceph-devel.
Discussion in the wip-hint thread is still on-going, but where it's
headed is unclear. This posting is simply to reflect the state of the
series after a thorough review by Alex.
Thanks,
Ilya
