block/throttle.c uses existing I/O throttle infrastructure inside a
block filter driver. I/O operations are intercepted in the filter's
read/write coroutines, and referred to block/throttle-groups.c

The driver can be used with the syntax
-drive driver=throttle,file.filename=foo.qcow2, \
        limits.iops-total=...,throttle-group=bar

The configuration flags and their semantics are identical to the
hardcoded throttling ones.

A node can be created referring to an existing group, and will overwrite
its limits if any are specified, otherwise they are retained.

What about .bdrv_co_get_block_status?

And if so, do you want my byte-based block status to go in first?  (Our
two series conflict, so we need to pick who needs to rebase on top of
the other).

No problem. My patch is in Kevin's branch for 2.11. Feel free to merge first if needed, I can rebase my patch if you do.
