That is one possibility. The other is to treat laundry as a lru type list under zone->lru_lock.

Dirty pages could be isolated from an atomic context. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
