Applied. Thanks
From: Andrii Nakryiko <andriin@fb.com> This patch set fixes bug in btf_dedup_is_equiv() check mishandling equivalence comparison between VOID kind in candidate type graph versus anonymous non-VOID kind in canonical type graph. Patch #1 fixes bug, by comparing candidate and canonical kinds for equality, before proceeding to kind-specific checks. Patch #2 adds a test case testing this specific scenario.
