kmemleak: Do not warn if an unknown object is freed
Catalin Marinas [Mon, 29 Jun 2009 16:13:57 +0000 (17:13 +0100)]
vmap'ed memory blocks are not tracked by kmemleak (yet) but they may be
released with vfree() which is tracked. The corresponding kmemleak
warning is only enabled in debug mode. Future patch will add support for
ioremap and vmap.
