From a1e4891fd48d298870b704c6eb48cba0da5ed6b1 Mon Sep 17 00:00:00 2001 From: Linus Torvalds Date: Sun, 22 May 2011 16:51:43 -0700 Subject: Remove prefetch() from and "netlabel_addrlist.h" Commit e66eed651fd1 ("list: remove prefetching from regular list iterators") removed the include of prefetch.h from list.h. The skbuff list traversal still had them. Quoth David Miller: "Please just remove the prefetches. Those are modelled after list.h as I intend to eventually convert SKB list handling to "struct list_head" but we're not there yet. Therefore if we kill prefetches from list.h we should kill it from these things in skbuff.h too."
