[proposal] binfmt_misc: pass binfmt_misc flags to the interpreter

[proposal] binfmt_misc: pass binfmt_misc flags to the interpreter

[Thorsten Glaser]

commit 2347961b11d4079deace3c81dceed460c08a8fc1

I would like to propose this commit from 5.12 for stable,
or rather, ask whether it’s a candidate and leave the exact
picking/backporting to the experts (if it has other commits
as prerequisites and/or later fixups).

This is because qemu-user needs it, and it arrived just too
late for the current Debian LTS kernel (5.10), and qemu-user
in Debian until yesterday had a workaround, but now doesn’t
because it’s in the stable kernel (6.1), so qemu-user-static
cannot be just used as-is on Debian LTS any more.

I’d like it to be applied to 5.10 (obviously), but perhaps
others would appreciate more broad coverage.

Thanks in advance,
//mirabilos

As this is a debian feature being backported, why not just add it to the
debian 5.10 kernel?

But, as it is a bugfix, I'll go queue it up now, thanks.

The maintainers prefer to upstream as much stuff as possible,
and it’s really a qemu-user feature, so it’s also helpful to
users of other distros.

Thank you!
