[Qemu-devel] [RFC PATCH v2 0/4] block-queue: Delay and batch metadata writes

[Kevin Wolf <kwolf@redhat.com>]

Still not quite there, but should be a bit more correct than the first RFC.
I still need to add proper error handling, the rest of block-queue itself
should be fairly complete. With respect to error handling, IDE, virtio-blk and
scsi-disk can deal with failed bdrv_(aio_)flush now, so just failing the next
flush seems to be a viable option now.

The integration into block.c and qcow2 is only a preliminary hack for now and
is going to be replaced.

  Add block-queue
