Is my thinking is correct ? And if yes then can some-one tell me where I can find the code related to that ? (I am just asking this for interest and its not so important to me, so not going to spend time for finding the source/result for this as I already have lot of work to do ! ;) ) Thanks, -- Fawad Lateef -- Kernelnewbies: Help each other learn about the Linux kernel.
