NAME
       skb_unshare - make a copy of a shared buffer

SYNOPSIS
       struct sk_buff * skb_unshare(struct sk_buff * skb, gfp_t pri);

ARGUMENTS
       skb
	   buffer to check

       pri
	   priority for memory allocation

DESCRIPTION
       If the socket buffer is a clone then this function creates a new copy
       of the data, drops a reference count on the old copy and returns the
       new copy with the reference count at 1. If the buffer is not a clone
       the original buffer is returned. When called with a spinlock held or
       from interrupt state pri must be GFP_ATOMIC

       NULL is returned on a memory allocation failure.
