29
+	  call that didn't upcall to the kernel to be cached temporarily in the
30

31

34

35

36

37
+	  An example of such a process is a pathwalk through a network
38
+	  filesystem in which each method needs to request an authentication
39

40
+	  (permission, d_revalidate, lookup, getxattr, getacl, ...).
