Dear Kernel maintainers,
              1. In tools/bpf/bpf_asm.c, the file opened at Line 40 may not closed within the function?
              Location: https://github.com/torvalds/linux/blob/5bfc75d92efd494db37f5c4c173d3639d4772966/tools/bpf/bpf_asm.c#L40-L49
 
              Should it be a bug? I can send patches for these.
 
Best,
Ryan
