I am curious how slab handles this, since it doesn't seem to refcount in the same way slub does? Now, I am still left with the original problem: __free_pages() here would be a superior solution, and the right thing to do. Should we just convert it - and then fix whoever we find to be abusing it (it doesn't mean anything, but I am running it on my systems since then - 0 problems), or should I just create a hacky put_accounted_page()? I really, really dislike the later. Anyone else would care to comment on this ? -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@xxxxxxxxx.
