pid: fix the do_each_pid_task() macro
Impact: macro side-effects fix This patch adds parenthesis around 'pid' in the do_each_pid_task macro to allow callers to pass in more complex parameters. e.g. do_each_pid_task(*pid, type, task) Signed-off-by: Steven Rostedt <srostedt@redhat.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
