slab: rename slab_break_gfp_order to slab_max_order
slab_break_gfp_order is more appropriately named slab_max_order since it enforces the maximum order size of slabs as long as a single object will still fit. Also rename BREAK_GFP_ORDER_{LO,HI} accordingly. Acked-by: Christoph Lameter <cl@linux.com> Signed-off-by: David Rientjes <rientjes@google.com> Signed-off-by: Pekka Enberg <penberg@kernel.org>
