Hi Raghu What you can do is you can add the process to a separate wait queue instead of adding it to default wait queue and then wakeup this process. So you can define a wait queue as wait_queue_head_t wq; And you can add a process to wait queue using init_waitqueue_head(&wq); interruptible_sleep_on(&wq); Now you can wake up this process using wake_up_interruptible(&wq); HTS -Aniruddha -----Original Message----- From: Raghu R.
