Subject: Re: [PATCH 02/10] ptrace: remove the extra wake_up_process() from ptrace_detach()

NAK.  Let's have the wake_up_state(task, TASK_TRACED|TASK_STOPPED) version
go in first.  That one will be more appropriate for -stable.  Even if we
shortly remove it entirely in mainline, having the more conservative
intermediate state in the git history will make any future problems more
susceptible to bisection.

Thanks,
Roland
