Comment 1 for bug 1551950

Simplified testcase:

/etc/apparmor.d/a

profile a {
    ^b {}
    ^c {}
}

apparmor_parser -r /etc/apparmor.d/a # load the profile
grep ^a /sys/kernel/security/apparmor/profiles # lists profile and both hats
echo 'profile a//b {}' | apparmor_parser -R # unload a//b (aka ^b)
apparmor_parser -r /etc/apparmor.d/a # reload from cache
grep ^a /sys/kernel/security/apparmor/profiles # will _not_ list a//b
