2013-08-14apparmor: change how profile replacement update is doneJohn Johansen1-11/+5
remove the use of replaced by chaining and move to profile invalidation and lookup to handle task replacement. Replacement chaining can result in large chains of profiles being pinned in memory when one profile in the chain is use. With implicit labeling this will be even more of a problem, so move to a direct lookup method. Signed-off-by: John Johansen <[email protected]>
