The file descriptor concept is the way it works in the rest of the kernel. It works for numerous drivers and subsystems (KVM, VFIO, UIO, ...), when you close a file descriptor handed out from any of those drivers (already in the kernel) all related resources will be freed. I don't see a reason why HSA drivers should break these expectations and be different. Joerg -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@xxxxxxxxx.
