OK, please see v3 rebased on top of "unexport ptrace_check_attach()" you
already applied.
I tried to update the comment in ptrace_check_attach(), and changed unfreeze()
to simply do WARN_ON() without if/return.
There is also the cosmetic change in 1/3,
- ptrace_signal_wake_up(child, task_is_traced(child));
+ ptrace_signal_wake_up(child, true);
in __ptrace_unlink().
Oleg.
