How to find out which part of code is changing a particular data structure.

[Rajat Jain]

Hi folks,

I have a memory location (One of the fields in a kernel data structure) and I want to track down the code that changes the value of that particular location. Some thing like a "watchpoint".

And this is early while I am still booting up. Can some one tell me if it is possible to do so?

Thanks,

Rajat
