Blacklist regex is too general

Hi folks!

I've wanted to measure the impact of packet duplication due to a raw socket.
To do so, I have to probe the kernel function 'raw_v4_input' in
net/ipv4/raw.c.
Unfortunately, the function name matches the regex defined at
dwflpp:4324, which is: blfn += "|raw_.*";.
On my opinion, the regex is too general, and there is no reason why it
shouldn't be allowed to probe 'raw_v4_input'.
It therefore might be necessary to rephrase the mentioned regex. :)

Cheers,
Alex
