+         If this is set, STACKLEAK metrics for every task are available in
+         the /proc file system. In particular, /proc/<pid>/stack_depth
+         shows the maximum kernel stack consumption for the current and
+         previous syscalls. Although this information is not precise, it
+         can be useful for estimating the STACKLEAK performance impact for
+         your workloads.
