[PATCH 00/16] virtio ring rework.
OK, this is (ab)uses some of Paolo's patches. The first 7 are
candidates for this merge window (maybe), the rest I'm not so sure
about.
Thanks,
Rusty.
Paolo Bonzini (3):
scatterlist: introduce sg_unmark_end
virtio-blk: reorganize virtblk_add_req
virtio-blk: use virtqueue_add_sgs on req path

[PATCH 00/12] block/bio, fs: convert put_page() to put_user_page*()
From: John Hubbard <jhubbard at nvidia.com>
Hi,
This is mostly Jerome's work, converting the block/bio and related areas
to call put_user_page*() instead of put_page(). Because I've changed
Jerome's patches, in some cases significantly, I'd like to get his
feedback before we actually leave him listed as the author (he might
want to disown some or all of these).

[PATCH 00/22] virtqueue_add_sgs, virtqueue_add_outbuf, virtqueue_add_inbuf
Add virtqueue_add_sgs which is more general than virtqueue_add_buf,
which makes virtio-scsi and virtio-blk nicer, then add virtqueue_add_inbuf
and virtqueue_add_outbuf which handle the more general case, and finally
delete virtqueue_add_buf().
I'm hoping this will be the final post of the whole series, and it can
move from my pending-rebases tree into virtio-next.
Thanks!
Rusty.
