Pass start and len to the rreq allocator. This should ensure that the fields are set so that ->init_request() can use them. Also add a parameter to indicates the origin of the request. Ceph can use this to tell whether to get caps. Changes ======= ver #3) - Change the author to me as Jeff feels that most of the patch is my changes now. ver #2) - Show the request origin in the netfs_rreq tracepoint.
