This patch adds simple file backed namespace support for NVMeOF target. The new file io-cmd-file.c is responsible for handling the code for I/O commands when ns is file backed. Also, we introduce mempools based slow path using sync I/Os for file backed ns to ensure forward progress under reclaim. The old block device based implementation is moved to io-cmd-bdev.c and use a "nvmet_bdev_" symbol prefix. The enable/disable calls are also move into the respective files.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
