From 481c5346d0981940ee63037eb53e4e37b0735c10 Mon Sep 17 00:00:00 2001 From: Christoph Lameter Date: Sat, 21 Jun 2008 16:46:35 -0700 Subject: Slab: Fix memory leak in fallback_alloc() The zonelist patches caused the loop that checks for available objects in permitted zones to not terminate immediately. One object per zone per allocation may be allocated and then abandoned. Break the loop when we have successfully allocated one object.
