| |
Hi Andi
Checking Christoph quicklist implementation, I found the same cache miss in free() than SLAB has.
/* common implementation * int virt_to_nid(const void *addr) { struct page *page = virt_to_page(addr); return page_to_nid(page); }
On some platforms (x86_64 for example), could we have a better implementation, not accessing struct page, but using phys_to_nid() ?
