From: KP Singh <kpsi...@google.com> # v2 -> v3
- Fixed an issue pointed out by Alexei, the helper should only be exposed to sleepable hooks. - Update the selftests to constrain the IMA policy udpate to a loopback filesystem specifically created for the test. Also, split this out from the LSM test. I dropped the Ack from this last patch since this is a re-write.
