Re: Random number generator in Linux kernel

[selvakumar nagendran <kernelselva@yahoo.com>]

        I think ur idea of generating a random number
with a seed will not be effective. The kernel comes up
with true random number generation by using the random
interaction of device drivers with the kernel. I think
that will be more effective than ur logic. It provides
true randomness and it avoids any guess. 
For more details u please refer the book ' Linux
kernel development' by Robert M Love Appendix C kernel
Random Number Generator. If u still want to stick to
ur own logic then u can implement it as a function
inside the kernel.
