The patch titled ptrace: introduce user_single_step_siginfo() helper has been removed from the -mm tree. Its filename was ptrace-introduce-user_single_step_siginfo-helper.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/ ------------------------------------------------------ Subject: ptrace: introduce user_single_step_siginfo() helper From: Oleg Nesterov <oleg@xxxxxxxxxx> Suggested by Roland. Currently there is no way to synthesize a single-stepping trap in the arch-independent manner. This patch adds the default helper which fills siginfo_t, arch/ can can override it. Architetures which implement user_enable_single_step() should add user_single_step_siginfo() also.
