+Note, we can't use 0, because it's a valid value for IO port access.

+Subject: zap_pid_ns_processes: clear TIF_NOTIFY_SIGNAL along with

+
+From: Oleg Nesterov <oleg@redhat.com>
+
+[ Upstream commit 7fea700e04bd3f424c2d836e98425782f97b494e ]
+
+kernel_wait4() doesn't sleep and returns -EINTR if there is no
+eligible child and signal_pending() is true.
+
+That is why zap_pid_ns_processes() clears TIF_SIGPENDING but this is not
+enough, it should also clear TIF_NOTIFY_SIGNAL to make signal_pending()
+return false and avoid a busy-wait loop.
