It looks like some of this discussion is still active, so it might be a little premature to implement this. That being said, I reviewed what you have. Overall it looks good to me.

I also think that in this case just extending the definition of a write request is preferable to encoding this stuff in a distinct new op, but I may be missing some information. -Alex > > Thanks, > > Ilya > > > Ilya Dryomov (6): > 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 > > drivers/block/rbd.c | 90 ++++++++++++++++++++++++++++----------- > include/linux/ceph/osd_client.h | 12 +++++- > include/linux/ceph/rados.h | 10 ++++- > net/ceph/osd_client.c | 32 ++++++++++++++ > 4 files changed, 117 insertions(+), 27 deletions(-) > -- To unsubscribe from this list: send the line "unsubscribe ceph-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
