Hi everybody, as teh object of this mail tells, I'd like to know if there is an easy way
to disable task rescheduling in the kernel.
I explain: I'm writing a device driver and so, I use the ioctl.
In one of my ioctl's, I'd like to have a non-interruptible part processed.
int Hscx_ioctl( struct inode *inode,
struct file *file,
unsigned int ioctl_num, /* Number of the ioctl to call */
unsigned long argP) /* Paramater to pass to the ioctl */
disable_task_rescheduling(); // what to use???
disable_interrupt(); // spin_lock_irqsave should be enough isn't it?
enable_task_rescheduling(); // what to use???
enable_interrupt(); // spin_unlock_irqrestore should be enough isn't it?
Could you give me a tip cause I've browsed the web and technical books and I can't find a solution.
Tks a lot
