[patch 04/10] SLUB: Avoid checking for a valid object before zeroing on the fast path

The fast path always results in a valid object. Move the check for the NULL pointer to the slow branch that calls __slab_alloc. Only __slab_alloc can return NULL if there is no memory available anymore and that case is exceedingly rare. Signed-off-by: Christoph Lameter <[EMAIL PROTECTED]> --- mm
