These are actually a few sets of patches but I'm just going to
post them as a single series this time.

[PATCH 1/9] ceph: use page_offset() in ceph_writepages_start()
Fixes a potential bug in ceph_writepages_start().
[PATCH 2/9] libceph: drop ceph_osd_request->r_con_filling_msg
Removes a no-longer-needed field, to simplify code.
[PATCH 3/9] libceph: record length of bio list with bio
[PATCH 4/9] libceph: record message data length
Has each message maintain its data length, so we can
avoid depending on what's in the message's header.
[PATCH 5/9] libceph: don't build request in ceph_osdc_new_request()
[PATCH 6/9] ceph: define ceph_writepages_osd_request()
[PATCH 7/9] ceph: kill ceph alloc_page_vec()
[PATCH 8/9] libceph: hold off building osd request
[PATCH 9/9] ceph: build osd request message later for writepages
Defers "building" a request message until right before
it's submitted to the osd client to start its execution.
Also stops having the length field in a message header
get updated by the file system code.
These all look good. The one thing I'm uncertain about is changing
the mempool allocation failure from a WARN to a BUG, but it seems
there's no good way to recover at that point.
