After the series, quorum doesn't only use the preferred interfaces, but the code becomes a little easier to follow and byte granularity requests are supported. There is probably still some potential for additional cleanups in a follow-up series, but this should already be enough to be worth merging. v2: - Patch 7: Change rounding in one more place [Eric] - Patch 9: Additional cleanup [Eric] v1 (from RFC): - Patch 1: Removed useless #include [Eric] - Patch 3: * Define QuorumCo at the top so that a later patch doesn't have to move it [Eric] * Renamed QuorumCo.i to QuorumCo.idx [Berto] * Removed useless co = NULL [Eric] - Patch 5/6: Reenter caller coroutine only after the last request [Berto] - Patch 6: Replace void cast by comment [Berto] - Patch 7: Change rounding [Eric/Berto] Kevin Wolf (9): coroutine: Introduce qemu_coroutine_enter_if_inactive() quorum: Remove s from quorum_aio_get() arguments quorum: Implement .bdrv_co_readv/writev quorum: Do cleanup in caller coroutine quorum: Inline quorum_aio_cb() quorum: Avoid bdrv_aio_writev() for rewrites quorum: Implement .bdrv_co_preadv/pwritev() quorum: Inline quorum_fifo_aio_cb() quorum: Clean up quorum_aio_get() block/quorum.c | 404 +++++++++++++++++++++++++---------------------- include/qemu/coroutine.h | 6 + util/qemu-coroutine.c | 7 + 3 files changed, 229 insertions(+), 188 deletions(-) -- 1.8.3.1
