Any news on this? What remains to be done, who needs to be harrassed?

Regards, Norbert
Christian was working on a new version but there is no update for 1 year.

[PATCH v2 1/2] binfmt_misc: cleanup on filesystem umount
https://lkml.org/lkml/2021/12/16/406
[PATCH v2 2/2] binfmt_misc: enable sandboxed mounts
https://lkml.org/lkml/2021/12/16/407

And personally I don't have the time to work on this.
I've actually rebased this a few weeks ago:
https://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs.git/log/?h=vfs.binfmt_misc
It has Acks, it's done. The only thing back then was Kees had wanted to
take this but never did. I'll ping him.
Hi! Can you resend this now that the merge window is closed? I looked at
it in your tree and it seems okay. I remain a bit nervous about exposing
it to unpriv access, but I'd like to give it a try. It'd be very useful!

Hate to be that guy, but did anything move closer towards upstream
since that post?
No rebase was needed -- I've dropped this in -next now. Let's see how it
goes!
