Hi, I was looking through UTLD3 and have some queries related the linux memory management code (kernel 2.6.26) I need to get a pointer to the task (process) that faulted and needs to have a page swapped in, so inside the handle_pte_fault() function I declared "struct task_struct *ptr" and just before do_swap_page() is called I assign "ptr = current" and do a printk of ptr->pid. I repeated the above inside the do_swap_page() function, just before grab_swap_token() is called. The question is : is the output of the printk statments as shown above giving me the correct pid, that is the pid of the task that caused the major page fault ? Putting this another way, I need to know if the functions mentioned above can go to sleep or be blocked i.e. can be preempted ? Also, how can I know by looking at the kernel code if a function is preemptible or not ?
