Merge branch 'support-flex-arrays'
Andrii Nakryiko says:
====================
Add support for flexible array accesses in a relocatable manner in BPF CO-RE.
It's a typical pattern in C, and kernel in particular, to provide
a fixed-length struct with zero-sized or dimensionless array at the end. In
such cases variable-sized array contents follows immediately after the end of
a struct. This patch set adds support for such access pattern by allowing
accesses to such arrays.
Patch #1 adds libbpf support. Patch #2 adds few test cases for validation.
