As pointed out in an earlier discussion [0] not all paths in bpftool's minimization logic handle the restrict type qualifier properly. Specifically, the gen min_core_btf command fails when encountering the corresponding BTF kind for a TYPE_EXISTS relocation (TYPE_MATCHES support was added earlier): > Error: unsupported kind: restrict (26) This patch set fixes this short coming.
