hi all, I was going through RML's book (ch. 2). There he mentions that having the new structure "thread_info" helps in calculating the offsets using assembly code rather easily. How does having a struct (which has a pointer to task_struct) stored on the top a process kernel stack be more advantageous than storing a pointer to task_struct itself on the same location!? Furthermore the assembly code used to get a pointer to thread_info masks the lower 13 bits to obtain the pointer. Does this mean that the size of thread_info is 8191 bytes (13 bits)?? I was trying to do a "sizeof" of struct thread_info from a sample prog. but was getting errors when i tried to include linux/thread_info.h.....so i thought i'll ask here! :) thanks, -mandeep -- Kernelnewbies: Help each other learn about the Linux kernel.
