Merge branch '"map_extra" and bloom filter fixups'

Joanne Koong says:

====================

There are 3 patches in this patchset:

1/3 - Bloom filter naming fixups (kernel/bpf/bloom_filter.c)

2/3 - Add alignment padding for map_extra, rearrange fields in
bpf_map struct to consolidate holes

3/3 - Bloom filter tests (prog_tests/bloom_filter_map):
Add test for successful userspace calls, some refactoring to
use bpf_create_map instead of bpf_create_map_xattr

v1 -> v2:
    * In prog_tests/bloom_filter_map: remove unneeded line break,
	also change the inner_map_test to use bpf_create_map instead
	of bpf_create_map_xattr.
    * Add acked-bys to commit messages
