Add riscv64 support (#14601)
In riscv64, the `syscall.Uname` function will return a uint8 slice.

    func main() {
      var buf syscall.Utsname
      fmt.Printf("Buffer Type: %T\n", buf.Release)
    }

    output:
      Buffer Type: [65]uint8

This is tested in the Arch Linux RISC-V 64 QEMU environment.

warn issues about large block I/O performance for Linux older than 4.0.0 (#14524)
This PR simply adds a warning message when it detects older kernel
versions and warn's them about potential performance issues on this
kernel.

The issue can be seen only with parallel I/O across all drives
on denser setups such as 90 drives or 45 drives per server configurations.
