Christoph Lameter 683d0baad3 SLUB: Use unique end pointer for each slab page. ... We use a NULL pointer on freelists to signal that there are no more objects. However the NULL pointers of all slabs match in contrast to the pointers to the real objects which are in different ranges for different slab pages. Change the end pointer to be a pointer to the first object and set bit 0. Every slab will then have a different end pointer. This is necessary to ensure that end markers can be matched to the source slab during cmpxchg_local. Bring back the use of the mapping field by SLUB since we would otherwise have to call a relatively expensive function page_address() in __slab_alloc(). Use of the mapping field allows avoiding a call to page_address() in various other functions as well. There is no need to change the page_mapping() function since bit 0 is set on the mapping as also for anonymous pages. page_mapping(slab_page) will therefore still return NULL although the mapping field is overloaded.
