Merge branch 'inner_map_spin_lock-fix'
Yonghong Song says:
====================
The inner_map_meta->spin_lock_off is not set correctly during
map creation for BPF_MAP_TYPE_ARRAY_OF_MAPS and BPF_MAP_TYPE_HASH_OF_MAPS.
This may lead verifier error due to misinformation.
This patch set fixed the issue with Patch #1 for the kernel change
and Patch #2 for enhanced selftest test_maps.
====================
