From cbb042f9e1292434e3cacb90e67d8d381aeac5a9 Mon Sep 17 00:00:00 2001 From: Herbert Xu Date: Mon, 20 Mar 2006 22:43:56 -0800 Subject: [NET]: Replace skb_pull/skb_postpull_rcsum with skb_pull_rcsum We're now starting to have quite a number of places that do skb_pull followed immediately by an skb_postpull_rcsum. We can merge these two operations into one function with skb_pull_rcsum. This makes sense since most pull operations on receive skb's need to update the checksum. I've decided to make this out-of-line since it is fairly big and the fast path where hardware checksums are enabled need to call csum_partial anyway. Since this is a brand new function we get to add an extra check on the len argument. As it is most callers of skb_pull ignore its return value which essentially means that there is no check on the len argument. Signed-off-by: Herbert Xu Signed-off-by: David S.
