Subject: [PATCH bpf-next 0/3] rename *_info_cnt to nr_*_info in bpf_prog_info

Before func_info and line_info are added to the kernel, there are several
fields in structure bpf_prog_info specifying the "count" of a user buffer, e.g.,
        __u32 nr_jited_ksyms;
        __u32 nr_jited_func_lens;
The naming convention has the prefix "nr_".

The func_info and line_info support added several fields
        __u32 func_info_cnt;
        __u32 line_info_cnt;
        __u32 jited_line_info_cnt;
to indicate the "count" of buffers func_info, line_info and jited_line_info.
The original intention is to keep the field names the same as those in
structure bpf_attr, so it will be clear that the "count" returned to user
space will be the same as the one passed to the kernel during prog load.

Unfortunately, the field names *_info_cnt are not consistent with
other existing fields in bpf_prog_info.
This patch set renamed the fields *_info_cnt to nr_*_info
to keep naming convention consistent.
