Hi, Vlastimil.
Thank you for your reply. Indeed, BTF can eliminate the existing problem
of data structure parsing. But as far as the current BCC[0] code is
concerned, more surgery may be required.
Now the bcc problem[1] should probably be solved by the bcc itself using
BTF, and should not bother the kernel. I hope the maintenance engineers
at BCC can agree with this. Thanks again.
