Hi all, I am working on Final year Computer Engineering project on paging in linux kernel . For this project I have to introduce a new flagbit in the descriptor of the page . I'll be using one of the flagbit that are not presently used. i am working on ia64 machine. As given in include/linux/page-flags.h currently only flag bits 0-19 are used and bits 32-63 are used as field for node information. so will it be feasible to use any of the unused flagbits from bit 20 to bit 32 for our purpose? -Atoka -- Kernelnewbies: Help each other learn about the Linux kernel.
