It seems like people are arguing in circles over this: Do we: 1. control potential memory usage by throttling I/Oor 2. Throttle I/O when memory is full I might lean toward (1) if we didn't already have a memory controller.But, we have one, and it works. Also, we *already* do (2) in thekernel, so it would seem to graft well onto existing mechanisms that wehave. I/O controllers should not worry about memory. They're going to have ahard enough time getting the I/O part right. :) Or, am I over-simplifying this? -- Dave _______________________________________________Containers mailing listContainers@xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx://lists.linux-foundation.org/mailman/listinfo/containers
