+.SH NAME
+skb_queue_head \- insert an sk_buff at the head of a list
+.SH SYNOPSIS
+.B #include <linux/skbuff.h>
+.HP
+.BI "void  __skb_queue_head(struct sk_buff_head " *list ", struct sk_buff " *newsk ");"
+.TP

+.SH DESCRIPTION
+The \fBskb_queue_head\fP function adds \fInewsk\fP to the head of \fIlist\fP.
+Specifically, it sets the list, next, and prev pointers in \fInewsk\fP, and
+increments the qlen element of \fIlist\fP.  It also rearranges the next
+and prev pointers in the existing head of \fIlist\fP before returning.
+.SH "RETURN VALUE"
+None.
+.SH NOTES
+It is important to note the difference between not only \fB__skb_queue_head\fP
+and \fBskb_queue_head\fP, but all the \fB__skb_\fP functions and their
+\fBskb_\fP counterparts.  Essentially, the \fB__skb_\fP functions are
+non-atomic, and should only be used with interrupts disabled.  As a convenience,
+the \fBskb_\fP functions are provided, which perform interrupt disable /
+enable wrapper functionality in addition to performing their specific tasks.
+.SH AVAILABILITY
