      bpf: fix build warnings and add function read_trace_pipe() · 5ed3ccbd
      Kaixu Xia authored
      There are two improvements in this patch:
       1. Fix the build warnings;
       2. Add function read_trace_pipe() to print the result on
          the screen;
      
      Before this patch, we can get the result through /sys/kernel/de
      bug/tracing/trace_pipe and get nothing on the screen.
      By applying this patch, the result can be printed on the screen.
        $ ./tracex6
