I am hacking a linux-2.0.32 kernel. I would like to create a special kind
of task which responds to things like system calls, signals, and interrupts
differently from other tasks. One possible solution is to add a field like
this to task_struct:
struct task_ops {
int (*syscall)(struct pt_regs regs);
int (*signal)(??);
int (*interrupt)(??);
};
struct task_ops default_task_ops;
...and call the right op in entry.S.
My question is: has anyone considered this? Thought of a better solution?
Rejected it? I'm not hot on i386 assembly, so I would rather not muck
about too much with entry.S.
