+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Section "pid_max" in Linux admin-guide/sysctl/kernel.rst says:
+
+| PID allocation wrap value.  When the kernel's next PID value
+| reaches this value, it wraps back to a minimum PID value.
+| PIDs of value "pid_max" or larger are not allocated.
+
+In particular, when pid_max == 10**N exactly, then the largest
+possible PID is 10**N - 1, i.e. the length is N.
