From bf690f59d0429c62de4db1234f16557eedcb39bf Mon Sep 17 00:00:00 2001 From: John Johansen Date: Sat, 10 Apr 2021 02:09:44 -0700 Subject: apparmor: cleanup shared permission struct The shared permissions struct has the stop field which is unneeded and the "reserved" subtree field commented which is needed. Also reorganize so that the entries are logically grouped.
