___slab_alloc() deactivate_slab() add_full(s, n, page); The page will be added to full list and the frozen is 0, right? __slab_free() prior = page->freelist; // prior is NULL was_frozen = new.frozen; // was_frozen is 0 ... /* * Slab was on no list before and will be * partially empty * We can defer the list move and instead * freeze it. */ new.frozen = 1; ... I don't understand why "Slab was on no list before"? Thanks, Xishi Qiu -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@xxxxxxxxx.
