[PATCH bpf 0/5] bpf: fix map permissions check and cleanup code around

[Anton Protopopov <a.s.protopopov@xxxxxxxxx>]

This series fixes a bug in the map_lookup_and_delete_elem() function which
should check for the FMODE_CAN_READ bit, because it returns data to user space.
The rest of commits fix some typos and comment in selftests and extend the
test_map_wronly test to cover the new check for the BPF_MAP_TYPE_STACK and
BPF_MAP_TYPE_QUEUE map types.

Anton Protopopov (5):
  selftests/bpf: fix a typo in test_maps
  selftests/bpf: cleanup some file descriptors in test_maps
  selftests/bpf: cleanup comments in test_maps
  bpf: fix map permissions check
