Subject: [PATCH bpf 0/3] bpf: fix bpffs/bpftool bitfield value printing

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.

Yonghong Song (3):
  bpf: fix bpffs bitfield pretty print
  tools/bpf: test btf bitfield with >=256 struct member offset
  tools/bpf: fix bpftool map dump with bitfields
