percpu: remove unit_size power-of-2 restriction Impact: allow unit_size to be arbitrary multiple of PAGE_SIZE In dynamic percpu allocator, there is no reason the unit size should be power of two. Remove the restriction. As non-power-of-two unit size means that empty chunks fall into the same slot index as lightly occupied chunks which is bad for reclaming. Reserve an extra slot for empty chunks. Signed-off-by: Tejun Heo <tj@kernel.org>
