Refactor to use queue based data chunks on the migration file. The SAVE command adds a chunk to the tail of the queue while the read() API finds the required chunk and returns its data. In case the queue is empty but the state of the migration file is MLX5_MIGF_STATE_COMPLETE, read() may not be blocked but will return 0 to indicate end of file. This is a step towards maintaining multiple images and their meta data (i.e. headers) on the migration file as part of next patches from the series. Note: At that point, we still use a single chunk on the migration file but becomes ready to support multiple.

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.
