Andrii Nakryiko says:

====================
BTF size resolution logic isn't always resolving type size correctly, leading
to erroneous map creation failures due to value size mismatch.

This patch set:
1. fixes the issue (patch #1);
2. adds tests for trickier cases (patch #2);
3. and converts few test cases utilizing BTF-defined maps, that previously
   couldn't use typedef'ed arrays due to kernel bug (patch #3).
