[PATCH 0/6] virtio_add_buf replacement.
OK, so I've spent a few days benchmarking. Turns out 80% of
virtio_add_buf cases are uni-directional (including the
always-performance-sensitive networking code), and that gets no
performance penalty (though tests with real networking would be
appreciated!).
I'm not reposting all the "convert driver to virtio_add_outbuf()"
patches: just the scsi one which I...

[RFC PATCH v1 0/2] virtio_net: Better low memory handling.
The following series applies to net-next.
The following series changes the low memory paths in virtio_net to allow
the driver to contribute to reclaim when memory is tight.
It attempts to rectify some performance problems we've seen where the
network performance drops significantly when memory is low. The working
theory is that while the driver contributes to memory pressure when
throughput

[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
Rusty Russell (13):
virtio_ring: virtqueue_add_sgs, to add multiple sgs.

[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.
