parentbpf: clean up bpf_prog_get_info_by_fd() (diff)
parenttools/bpf: rename *_info_cnt to nr_*_info (diff)
Merge branch 'rename-info_cnt-to-nr_info'
Yonghong Song says: ==================== 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. ==================== Signed-off-by: Alexei Starovoitov <ast@kernel.org>
