From 6f912042256c12b0927438122594f5379b364f5d Mon Sep 17 00:00:00 2001 From: KAMEZAWA Hiroyuki Date: Mon, 10 Apr 2006 22:52:50 -0700 Subject: [PATCH] for_each_possible_cpu: network codes for_each_cpu() actually iterates across all possible CPUs. We've had mistakes in the past where people were using for_each_cpu() where they should have been iterating across only online or present CPUs. This is inefficient and possibly buggy. We're renaming for_each_cpu() to for_each_possible_cpu() to avoid this in the future. This patch replaces for_each_cpu with for_each_possible_cpu under /net Signed-off-by: KAMEZAWA Hiroyuki Acked-by: "David S.
