NAME

       skb_queue_tail - queue a buffer at the list tail

SYNOPSIS

       void skb_queue_tail(struct sk_buff_head * list, struct sk_buff * newsk);

ARGUMENTS

       list
	   list to use

       newsk
	   buffer to queue

DESCRIPTION

       Queue a buffer at the tail of the list. This function takes the list lock and can be used safely with other locking sk_buff functions
       safely.

       A buffer cannot be placed on two lists at the same time.

NAME

       blk_init_queue - prepare a request queue for use with a block device

SYNOPSIS

       struct request_queue * blk_init_queue(request_fn_proc * rfn, spinlock_t * lock);

ARGUMENTS

       rfn
	   The function to be called to process requests that have been placed on the queue.

       lock
	   Request queue spin lock

DESCRIPTION

       If a block device wishes to use the standard request handling procedures, which sorts requests and coalesces adjacent requests, then it
       must call blk_init_queue. The function rfn will be called when there are requests on the queue that need to be processed. If the device
       supports plugging, then rfn may not be called immediately when requests are available on the queue, but may be called at some time later
       instead. Plugged queues are generally unplugged when a buffer belonging to one of the requests on the queue is needed, or due to memory
       pressure.

       rfn is not required, or even expected, to remove all requests off the queue, but only as many as it can handle at a time. If it does leave
       requests on the queue, it is responsible for arranging that the requests get dealt with eventually.

       The queue spin lock must be held while manipulating the requests on the request queue; this lock will be taken also from interrupt context,
       so irq disabling is needed for it.

       Function returns a pointer to the initialized request queue, or NULL if it didn't succeed.

NOTE

       blk_init_queue must be paired with a blk_cleanup_queue call when the block device is deactivated (such as at module unload).
