[PATCH bpf-next v3 0/3] Implement bpf_ima_inode_hash

[KP Singh]

From: KP Singh <kpsingh at 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.

KP Singh (3):
  ima: Implement ima_inode_hash
  bpf: Add a BPF helper for getting the IMA hash of an inode
  bpf: Add a selftest for bpf_ima_inode_hash
