+Each cgroup in the v2 hierarchy contains the following files,
+which can be used to view and set limits on the number
+of descendant cgroups under that cgroup:

+.IR cgroup.max.depth " (since Linux 4.14)"
+.\" commit 1a926e0bbab83bae8207d05a533173425e0496d1
+This file defines a limit on the depth of nesting of descendant cgroups.
+A value of 0 in this file means that no descendant cgroups can be created.
+An attempt to create a descendant whose nesting level exceeds
+the limit fails
+.RI ( mkdir (2)
+fails with the error
+.BR EAGAIN ).
+.IP
+Writing the string
+.IR """max"""
+to this file means that no limit is imposed.
