Looks like Stefan gave you an R-B for the series; do we just need an
ACK by the block maintainers at this point or is there someone
specific you're hoping will review this?

Hi John,

I figure a maintainer's R-b doesn't imply the patches being merged into
the tree.  Hence I'm waiting for the notice that they actually are merged.

Please let me know if the process should be different.

Hi Andrey,
Kevin is away right now but seemed happy enough when I mentioned this
series to him, so I have merged this into my own tree:

  https://gitlab.com/stefanha/qemu block

Sorry that your patch series have not been merged in a timely manner.

Hi Stefan,
Good news! Thank you for the notice.

When you have some time would you mind taking a look at these series as
well:

https://lists.nongnu.org/archive/html/qemu-block/2023-06/msg00068.html
https://lists.nongnu.org/archive/html/qemu-block/2023-07/msg00106.html

They've been hanging in the list for weeks (probably even longer than
this one) with little to no feedback.  Would be nice to know if people
find those changes useful at all.

Thanks in advance!

Andrey

Kevin will be back on Tuesday and Hanna Czenczek said she may have time
to look before then. Hopefully they will get taken care of soon.

has been sent as 4/3 patch today by Andrey. Unit tests
are broken at the moment.
