Could be either (but it depends on the kernel version as well since there were some kmemleak fixes during the -rc stages). Can you merge the "kmemleak-fixes" branch from git://linux-arm.org/linux-2.6.git (or just pick http://www.linux-arm.org/git?p=linux-2.6.git;a=commitdiff;h=4d2b5efa46639b704fd5db1ccd3bdf51cadda50e which ensures that all thread stacks are scanned)? Are the same leaks still reported reported after a few "echo scan > /sys/kernel/debug/kmemleak"? If not, they are just transient leaks, happening especially on SMP systems. If they are still present, could you please also post the relevant .config entries?
