Yes, this is one of the problems linux kernel still has, which should be solved. But I believe this should be done in the linux memory management layer including the cgroup memory controller, which has to work correctly on any type of device with various access speeds. I think it's better that I/O controllers should only focus on flow of I/O requests. This approach will keep the implementation of linux kernel simple. > Buffered write I/O is also related with cache system. > We must consider this problem as I/O control. > I don't have a good way which can resolve this problems. > Thank you, Hirokazu Takahashi. _______________________________________________ Containers mailing list Containers@xxxxxxxxxxxxxxxxxxxxxxxxxx https://lists.linux-foundation.org/mailman/listinfo/containers
