Just wondering :) Yeah, something funky is probably going on. But, the "reclaimable" ones aren't guaranteed to be reclaimable. It just means that we can usually reclaim most of them. If you have a refcount leak on an object or something like that, they're effectively unreclaimable still. So, either way, the next step is to see which slab it was that blew up. -- Dave -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
