 /**
+ * Indicates support for POSIX ACL.
+ *
+ * If this feature is enabled, the kernel will cache and have
+ * responsibility for enforcing ACLs. ACL will be stored as xattrs and
+ * passed to userspace, which is responsible for updating the ACLs in
+ * the filesystem, keeping the file mode in sync with the ACL, and
+ * ensuring inheritance of default ACLs when new filesystem nodes are
+ * created. Note that this requires that the file system is able to
+ * parse and interpret the xattr representation of ACLs.
+ *
+ * This feature is disabled by default.
