From 722e2ee09b8dfc2ac5eedb802dc0d227702df084 Mon Sep 17 00:00:00 2001 From: Stephen Wilson Date: Tue, 24 May 2011 17:12:44 -0700 Subject: [PATCH] mm: make gather_stats() type-safe and remove forward declaration Improve the prototype of gather_stats() to take a struct numa_maps as argument instead of a generic void *. Update all callers to make the required type explicit. Since gather_stats() is not needed before its definition and is scheduled to be moved out of mempolicy.c the declaration is removed as well.
