The patch titled Subject: ptrace: don't send SIGTRAP on exec if SEIZED has been removed from the -mm tree. Its filename was ptrace-dont-send-sigtrap-on-exec-if-seized.patch This patch was dropped because it was merged into mainline or a subsystem tree The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/ ------------------------------------------------------ From: Oleg Nesterov <oleg@xxxxxxxxxx> Subject: ptrace: don't send SIGTRAP on exec if SEIZED ptrace_event(PTRACE_EVENT_EXEC) sends SIGTRAP if PT_TRACE_EXEC is not set. This is because this SIGTRAP predates PTRACE_O_TRACEEXEC option, we do not need/want this with PT_SEIZED which can set the options during attach.
