SubjectRe: do_syslog/__down_trylock lockup in current BK

the following assert triggers and catches the lockup:

--- linux/kernel/exit.c.orig Mon Sep 9 21:59:24 2002
+++ linux/kernel/exit.c Mon Sep 9 22:38:44 2002
@@ -461,6 +461,8 @@
ptrace_unlink (p);

list_del_init(&p->sibling);
+ if (p->parent == father && p->parent == p->real_parent)
+ BUG();
p->parent = p->real_parent;
list_add_tail(&p->sibling, &p->parent->children);
}
so somehow we can end up having parent == real_parent?
