[Bug 615947] [NEW] AppArmor: kernel module fails to handle namespace removal correctly

[John Johansen]

Public bug reported:

As reported on lkml, there is a bug in AppArmor profile namespace
removal that can lead to an oops are deadlock, when the namespace is
specified without a profile.

eg. If the profile namespace foo, extists in the kernel
echo -n ":foo:" >/sys/kernel/security/apparmor/.remove

will trigger this bug.
