qvm-kill -- bug ???

[haaber]

Hi observed that killing sys-net will kill all VM's that depend on it as
well, which was not the case little time ago. I consider this a bug, but
it has maybe some intention?? Thanks for comments. Bernhard

It is indeed a bug: Linux’s netfront driver failed to properly clean up
when the backend dies, causing a kernel panic soon afterwards. The bug
has been fixed in kernels from the updates-testing repository. See
https://lore.kernel.org/xen-devel/20220220134202.2...@invisiblethingslab.com/
and https://github.com/QubesOS/qubes-issues/issues/7257 for details.
Marek, time to push the fix to stable?
