As pure cleanup, this patch removes PERCPU_ENOUGH_ROOM which is not used any more. That is, no code refers to the definition. Acked-by: Christoph Lameter <cl@linux.com> Signed-off-by: Jungseok Lee <jungseoklee85@gmail.com> --- I've kept Acked-by from Christoph since there is no change in generic percpu code between v1 and v2.
