Hi all. Here is minimal structured-read extension implementation for nbd.
It is needed mostly to implement nbd block-status extension over it, so
it is minimal.
It's based on my three patches, currently on pull-request stage:
block/nbd-client: refactor nbd_co_receive_reply
block/nbd-client: simplify check in nbd_co_receive_reply
block/nbd-client: nbd_co_send_request: fix return code
clone: tag up-nbd-minimal-structured-read-v1 from
https://src.openvz.org/scm/~vsementsov/qemu.git
online:
https://src.openvz.org/users/vsementsov/repos/qemu/browse?at=up-nbd-minimal-structured-read-v1
Note: actually it's a continuation of a part of my series "nbd: BLOCK_STATUS",
but it was sent about half a year ago, so let's consider it as new series.
