Hi,
It does resolve all the warnings concerned.
But could we also exclude documentation type blocks like:
/**
* @size size of access
*/
There were quite a few of these in include/linux/instrumented.

And also it isn't case sensitive. So the line
"the the word is repeated" generates a warning, but
"The the word is repeated" doesn't generate anything.

Thanks,
Dwaipayan.
