The previous BTF kind_flag support patch set introduced a bug for kernel bpffs pretty printing and another bug for bpftool map pretty printing. If a bitfield struct member offset is greater than 256 bits, printed value for that struct member will be incorrect.
Patch #1 fixed the bug in kernel bpffs pretty printing. Patch #2 enhanced the test_btf test case to cover the issue exposed by patch #1. Patch #3 fixed the bug in bpftool map pretty printing.
