Add a new NVME_IOCTL_IO64_CMD_VEC ioctl that works like the existing NVME_IOCTL_IO64_CMD ioctl except that it takes and array of iovecs and thus supports vectored I/O. - cmd.addr is base address of user iovec array - cmd.vec_cnt is count of iovec array elements This patch does not include vectored-variant for admin-commands as most of them are light on buffers and likely to have low invocation frequency.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
