Subject: skb allocation size question
Date: Wed, 1 Sep 2010 11:51:02 -0700 [thread overview]
Message-ID: <201009011151.02639.awilliams@atheros.com> (raw)
Hi,
I have been trying to track down an issue in one of our drivers with SKB
allocation and in my research I came across something that seems a bit
strange. In __alloc_skb, a block for the data allocates size + sizeof(struct
skb_shared_info) bytes, yet skb->truesize is set to size + sizeof(struct
sk_buff). Is there a reason for this discrepancy?
