[Qemu-devel] [PATCH v3 0/9] virtio-blk: Converge VirtIOBlockRequest into VirtIOBlockReq

[Fam Zheng <famz@redhat.com>]

This unifies the request structure used by dataplane and non-dataplane code,
while dropping unnessary fields for bounce buffer and read flag.

Applies on top of Stefan's block tree.

v3: Address Paolo's comments:

[06/09] virtio-blk: Use VirtIOBlockReq.in to drop VirtIOBlockReq.inhdr
        Add assertion and comments on inhdr.
        Fix the offset and iov_discard_back.

[08/09] virtio-blk: Fill in VirtIOBlockReq.out in dataplane code
        Allocate req in process_request.

[09/09] virtio-blk: Fix and clean up the in_sg and out_sg check
        New.
