[PATCH] Keys: Remove key duplication
Remove the key duplication stuff since there's nothing that uses it, no way to get at it and it's awkward to deal with for LSM purposes. Signed-off-by: David Howells <dhowells@redhat.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

- This method will be called with the source key's semaphore read-locked to

- This method does not have to lock the destination key in order to attach a
