crash in 'wake_up_interruptible()' on SMP

2006-12-14 Thread kiran kumar
this to point that 'spin_lock_irqsave/spin_lock_irqrestore' is issued only within waitQ. If i either not use 'unlocked_ioctl()' i.e. use ioctl() (or)comment out 'wake_up_interruptible()' call I don't see the crash. Is wake_up_interruptible SMP safe??? Regards, kiran
