I looked up that line in the source and found this piece of code:
full_free = 0; p = searchp->slabs_free.next; while (p != &searchp->slabs_free) { slabp = list_entry(p, slab_t, list); if (slabp->inuse) BUG(); full_free++; p = p->next; }
Could it be a race with this particular slabp being taken in use by another CPU at this very moment?
