Hello,
This series adds support for CEPH_OSD_OP_SETALLOCHINT osd op to libceph
along with adjusting rbd to make use of it. The rationale and the
basic desing was outlined in the "rados io hints" thread on ceph-devel
about a month ago.
Thanks,
Ilya

libceph: encode CEPH_OSD_OP_FLAG_* op flags
libceph: add support for CEPH_OSD_OP_SETALLOCHINT osd op
libceph: bump CEPH_OSD_MAX_OP to 3
rbd: do not hard-code CEPH_OSD_MAX_OP in rbd_osd_req_callback()
rbd: num_ops parameter for rbd_osd_req_create()
rbd: prefix rbd writes with CEPH_OSD_OP_SETALLOCHINT osd op
