From 6700ec65c207068a81a535e9dca616fefac21671 Mon Sep 17 00:00:00 2001 From: Ingo Molnar Date: Sun, 15 Feb 2009 21:18:17 +0100 Subject: [PATCH] lockdep: annotate reclaim context (__GFP_NOFS), fix MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Impact: fix build warning Fix: mm/vmscan.c: In function ‘kswapd’: mm/vmscan.c:1969: warning: ISO C90 forbids mixed declarations and code node_to_cpumask_ptr(cpumask, pgdat->node_id), has a side-effect: it defines the 'cpumask' local variable as well, so it has to go into the variable definition section. Sidenote: it might make sense to make this purpose of these macros more apparent, by naming them the standard way, such as: DEFINE_node_to_cpumask_ptr(cpumask, pgdat->node_id); (But that is outside the scope of this patch.)
