Move signal sending event to events/signal.h. This patch also renames sched_signal_send event to signal_generate. Changes in v4: - Fix a typo of task_struct pointer. Changes in v3: - Add docbook style comments Changes in v2: - Add siginfo argument - Add siginfo storing macro Signed-off-by: Masami Hiramatsu <mhiramat@redhat.com> Reviewed-by: Jason Baron <jbaron@redhat.com> Acked-by: Roland McGrath <roland@redhat.com> Cc: systemtap <systemtap@sources.redhat.com> Cc: DLE <dle-develop@lists.sourceforge.net> Cc: Oleg Nesterov <oleg@redhat.com> LKML-Reference: <20091124215645.30449.60208.stgit@dhcp-100-2-132.bos.redhat.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
