Message-ID: <20110624153439.GD9346@redhat.com> Date: Fri, 24 Jun 2011 17:34:39 +0200 From: Oleg Nesterov <oleg@...hat.com> To: Tejun Heo <tj@...nel.org>, Linus Torvalds <torvalds@...ux-foundation.org> Cc: vda.linux@...glemail.com, jan.kratochvil@...hat.com, pedro@...esourcery.com, linux-kernel@...r.kernel.org Subject: [PATCH 3/3] ptrace: wait_consider_task: s/same_thread_group/ptrace_reparented/ wait_consider_task() checks same_thread_group(parent, real_parent), this is the open-coded ptrace_reparented(). __ptrace_detach() remains the only function which has to check this by hand, although we could reorganize the code to delay __ptrace_unlink.
