Message-ID: <4F047243.3010009@redhat.com> Date: Wed, 04 Jan 2012 16:37:39 +0100 From: Denys Vlasenko <dvlasenk@...hat.com> To: Oleg Nesterov <oleg@...hat.com>, Tejun Heo <tj@...nel.org> CC: linux-kernel@...r.kernel.org, Denys Vlasenko <vda.linux@...glemail.com> Subject: [PATCH] renumber PTRACE_EVENT_STOP so that future PTRACE_O_TRACEfoo PTRACE_EVENT_foo and PTRACE_O_TRACEfoo used to match. New PTRACE_EVENT_STOP is the first event which has no corresponding PTRACE_O_TRACE option. If we will ever want to add another such option, its PTRACE_EVENT's value will collide with PTRACE_EVENT_STOP's value. This patch changes PTRACE_EVENT_STOP value to prevent this. While at it, added comment - the one above, "Wait extended result codes for the above trace options", is not true for PTRACE_EVENT_STOP.
