My "[PATCH v5 0/9] Allow changing bs->file on reopen" supersedes the "subject" part of the series. I think we now should start from taking it. Hmm, and I should check, does it conflict with recently merged block-permission-folloup and with beginning of "[PATCH v4 00/35] block: publish backup-top filter" which is already almost reviewed by Max and should land soon I hope (ohh, seems I should issue v5 for python conflictes).

So, I propose the following plan:

1. I'll rebase and send "block: publish backup-top filter" series today-tomorrow. It's big, and mostly reviewed, let's not lose r-bs by rebases.

2. I'll rebase and send if needed (if it conflicts with master and/or [1]) "[PATCH v5 0/9] Allow changing bs->file on reopen"

3. Then we'll decide what to do with the rest. Finally, I can take it if I have some time (the head is spinning from the number of tasks ;)

I also think that we can drop x- prefix even without supporting of multiple reopen, and implement it later as an option. QAPI interface is powerful enough for such enhancements.
