2007-04-25[SK_BUFF]: Introduce skb_reset_mac_header(skb)Arnaldo Carvalho de Melo
For the common, open coded 'skb->mac.raw = skb->data' operation, so that we can later turn skb->mac.raw into a offset, reducing the size of struct sk_buff in 64bit land while possibly keeping it as a pointer on 32bit. This one touches just the most simple case, next will handle the slightly more "complex" cases. Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com> Signed-off-by: David S.

2007-02-12[PATCH] mark struct file_operations const 3Arjan van de Ven
Many struct file_operations in the kernel can be "const". Marking them const moves these to the .rodata section, which avoids false sharing with potential dirty data. In addition it'll catch accidental writes at compile time to these shared resources.

2006-12-22[PATCH] fix aoe without scatter-gather [Bug 7662]Ed L. Cashin
Fix a bug that only appears when AoE goes over a network card that does not support scatter-gather. The headers in the linear part of the skb appeared to be larger than they really were, resulting in data that was offset by 24 bytes. This patch eliminates the offset data on cards that don't support scatter-gather or have had scatter-gather turned off. There remains an unrelated issue that I'll address in a separate email.

2006-10-18aoe: zero copy write 1 of 2Ed L. Cashin
Avoid memory copy on writes. (This patch depends on fixes in patch 9 to follow.) Although skb->len should not be set when working with linear skbuffs, the skb->tail pointer maintained by skb_put/skb_trim is not relevant to what happens when the skb_fill_page_desc function is called. This issue was raised without comment in linux-kernel and netdev earlier this month: http://thread.gmane.org/gmane.linux.kernel/446474/ http://thread.gmane.org/gmane.linux.network/45444/ So until there is something analogous to skb_put that works for zero-copy write skbuffs, we will do what the other callers of skb_fill_page_desc are doing.

2006-06-17[NET]: Clean up skb_linearizeHerbert Xu
The linearisation operation doesn't need to be super-optimised. So we can replace __skb_linearize with __pskb_pull_tail which does the same thing but is more general. Also, most users of skb_linearize end up testing whether the skb is linear or not so it helps to make skb_linearize do just that. Some callers of skb_linearize also use it to copy cloned data, so it's useful to have a new function skb_linearize_cow to copy the data if it's either non-linear or cloned. Last but not least, I've removed the gfp argument since nobody uses it anymore. If it's ever needed we can easily add it back.

2006-01-08[PATCH] Add block_device_operations.getgeo block device methodChristoph Hellwig
HDIO_GETGEO is implemented in most block drivers, and all of them have to duplicate the code to copy the structure to userspace, as well as getting the start sector. This patch moves that to common code [1] and adds a ->getgeo method to fill out the raw kernel hd_geometry structure. For many drivers this means ->ioctl can go away now. [1] the s390 block drivers are odd in this respect. xpram sets ->start to 4 always which seems more than odd, and the dasd driver shifts the start offset around, probably because of it's non-standard sector size.
