NAME
       __pskb_copy - create copy of an sk_buff with private head.

SYNOPSIS
       struct sk_buff * __pskb_copy(struct sk_buff * skb, int headroom,
				    gfp_t gfp_mask);

ARGUMENTS
       skb
	   buffer to copy

       headroom
	   headroom of new skb

       gfp_mask
	   allocation priority

DESCRIPTION
       Make a copy of both an sk_buff and part of its data, located in header.
       Fragmented data remain shared. This is used when the caller wishes to
       modify only header of sk_buff and needs private copy of the header to
       alter. Returns NULL on failure or the pointer to the buffer on success.
       The returned buffer has a reference count of 1.
