Hi,
It's the last REDIFF, but i'm not replacing yield() with
schedule_timeout() because there's a nicedelay() (maybe the
usecs need to be tuned below) there:
static inline void nicedelay(unsigned long usecs)
{
current->state = TASK_INTERRUPTIBLE;
schedule_timeout(HZ);
return;
}
Hope that helps,
Gustavo Franco
