[I forgot to cc the uml-devel list while sending the patch.]
This patch brings back the functionality of stopping user mode linux
with the help of mconsole.
I tested it for six hours and read the code which could be impacted by
this change, so it should work fine, but I am very inexperienced and
new to the kernel and C, so I could have made a mistake somewhere.
I had two ideas, and this one was the less invasive of the two. If
this is not the right way to fix this, I can send in my second idea in
a few days.
