[Qemu-devel] [RFC PATCH v3 0/4] block-queue: Delay and batch metadata writes

[Kevin Wolf <kwolf@redhat.com>]

block-queue itself looks more or less ready to me now, the rest is
possible bug fixes and addressing review comments. So please, give
the first three patches a good review, they are in their final version
otherwise.

This series is only marked RFC because proper qcow2 integration is
missing and merging block-queue doesn't make much sense without a user.

Patch 4/4 contains a hackish version of qcow2 integration which I think
should fully work (I think I addressed Stefan's comment), but is too
ugly to be merged.
