Brian Atkinson 1862c1c0a8 Removing old code outside of 4.18 kernsls ... There were checks still in place to verify we could completely use iov_iter's on the Linux side. All interfaces are available as of kernel 4.18, so there is no reason to check whether we should use that interface at this point. This PR completely removes the UIO_USERSPACE type. It also removes the check for the direct_IO interface checks.
