From 670c02c2bfd2c8a305a90f5285409a7b0a8fd630 Mon Sep 17 00:00:00 2001 From: John Hawkes Date: Thu, 13 Oct 2005 09:30:31 -0700 Subject: [NET]: Wider use of for_each_*cpu() In 'net' change the explicit use of for-loops and NR_CPUS into the general for_each_cpu() or for_each_online_cpu() constructs, as appropriate. This widens the scope of potential future optimizations of the general constructs, as well as takes advantage of the existing optimizations of first_cpu() and next_cpu(), which is advantageous when the true CPU count is much smaller than NR_CPUS.
