Subject: [PATCH bpf 0/2] fix map_lookup_elem return value for queue/stack map

This set fixes map_lookup_elem return value for queue/stack map.
Also adds verifier tests to check whether verifier prevents lookup on
these maps.

Note that patch 2 isn't dependant on patch 1. The verifier prevents
lookup on queue/stack map because key size is zero.

Prashant Bhole (2):
  bpf: queue/stack map, fix return value of map_lookup_elem
  bpf: test_verifier, test for lookup on queue/stack maps
