Hi,

/proc has no way to indicate whether tasks share an address space.
This one-liner patch adds a new ASID: field to /proc/<pid>/status so
there's some way to see address-space sharing between tasks.

While this is hardly a bug-fix, it is a pretty useful thing to know
which is otherwise completely absent.

	J

Obviously, this should be:

+	buffer += sprintf("ASID:\t%p\n", mm);

for consistency.
