Now that the commit: <b662000aff84> ("bpftool: Adding support for BTF
program names") supported show the full prog name, we can also use
the full prog name more than 16 (BPF_OBJ_NAME_LEN) chars in prog
subcommand, such as "bpftool prog show name PROG_NAME".

Thanks! But you mean you want something like this, correct?
# ./bpftool prog pin \
name prog_with_a_very_long_name /sys/fs/bpf/foo
This is already possible since commit d55dfe587bc0 ("bpftool: Remove
BPF_OBJ_NAME_LEN restriction when looking up bpf program by name"). Your
first version of the patch was based on a version that didn't have this
commit, but bpftool from bpf-next already supports this.
