As a consequence, the kernel is not allowed to write memory into the swap space. If a user pins too much memory, the system can run out of memory, and the kernel terminates processes to free up more memory. Therefore, memory pinning is a privileged operation. orchard theatre dartford christmasWebRDMA is a feature that enables network adapters to transfer data directly between each other without requiring the main processor of the system to be part of that transfer.
