Hi,
Before calling get_pid the state of child
is set to TASK_UNINTERRUPTIBLE and after get_pid
it is changed to TASK_RUNNNING.Why ?? Is it possbile
that a process may leave the CPU during get_pid?
Can any body tell me how linux is ensuring that
scheduling can not happen when a process is executing
in a system call and timer interrupt has occured.
Please do a CC to me also.
Thanks in advance
Ashish
