slub: add missed accounting
With per-cpu partial list, slab is added to partial list first and then moved to node list. The __slab_free() code path for add/remove_partial is almost deprecated(except for slub debug). But we forget to account add/remove_partial when move per-cpu partial pages to node list, so the statistics for such events are always 0. Add corresponding accounting. This is against the patch "slub: use correct parameter to add a page to partial list tail" Acked-by: Christoph Lameter <cl@linux.com> Signed-off-by: Shaohua Li <shaohua.li@intel.com> Signed-off-by: Pekka Enberg <penberg@kernel.org>
