netfs: Refactor arguments for netfs_alloc_read_request
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.
