Before commit c5459b829b ("LSM: Plumb visibility into optional "enabled"
state"), /sys/module/apparmor/parameters/enabled would show "Y" or "N"
since it was using the "bool" handler. After being changed to "int",
this switched to "1" or "0", breaking the userspace AppArmor detection
of dbus-broker. This restores the Y/N output while keeping the LSM
infrastructure happy.
Before:
$ cat /sys/module/apparmor/parameters/enabled
1
After:
$ cat /sys/module/apparmor/parameters/enabled
Y
