Anyway, your proposal comes up every few years, in different ways. Please research the past proposals for why this keeps failing and perhaps you should just fix up your userspace code instead? Also, look at attempts like the introduction of the readfile syscall as well, if you want to remove the open/read/close set of syscalls into one, but even that isn't all that useful for real-world applications, as you can today use the io_uring api to achieve almost the same throughput if really needed. good luck! greg k-h
