Subjectsmall patch - 2.4.21-pre7 net/core/bk
From
Date
Maybe i just don't understeand this part of code, but i think we should
not give calling driver five chances :)

/* Get the HEAD */
---------------------------------------------------------------
Also, i am bit confused with this part :
/* Get the DATA. Size must match skb_add_mtu(). */
size = SKB_DATA_ALIGN(size);
data = kmalloc(size + sizeof(struct skb_shared_info), gfp_mask);
if (data == NULL)
goto nodata;
/* XXX: does not include slab overhead */
skb->truesize = size + sizeof(struct sk_buff);
can anybody explain me please why skb->truesize gets size+sizeof(struct
sk_buff) (acording to XXX above it, it is incorrect).
