There does not seem to be an easy way to deal with this. Some thought needs to go into how memoryless node handling relates to per cpu lists and locking. List handling issues need to be addressed before SLQB. can work reliably. The same issues can surface on x86 platforms with weird NUMA memory setups. Or just allow SLQB for !NUMA configurations and merge it now. -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
