i have compiled and installed kernel 2.6.28.7 on my machine

in my machine in sched.h definition if task_struct is ....contains no mm field ...so the error ...
struct task_struct {

struct desc_struct ldt[3];
/* tss for this task */
struct tss_struct tss;
};
but in lxr i found
definition of task_struct is totally different in same version 2.6.28.7 it contains many more fields than what i found in my kernel.
even mm too
how and why are they different i dont understand ..
