/proc enhancement

[George Kola]

  We are working on a project to enhance linux /proc.
This is of particular importance to the 'Paradayn'
project (cs.wisc.edu/paradyn). 
  We want to add the ability to specifically trace a
set of system calls and the ability to trace  the
system call entry or exit or both. For this we wanted
to add two structs to

struct task_struct in include/linux/sched.h

struct  syscall_set {
   char traced[8];
}

we want to add 

struct syscall_set entry,exit; to task_struct in 
include/linux/sched.h

In the beginning of task_struct we found that

struct task_struct {
	/*
	 * offsets of these are hardcoded elsewhere - touch
with care
	 */

          We want to know what we would be breaking if
we add the structs at the end ? (so that we can fix
them)

         Also how do we initialize it in 
#define INIT_TASK(tsk) (we want to set all bits in the
struct to 1).

Thanks,
George
