Added a new status flag named MPT3_DIAG_BUFFER_IS_APP_OWNED and it will set whenever application registers the diag buffer & it will be cleared when application unregisters the buffer. When this flag is enabled, and if application issues diag buffer register command without releasing the buffer, then register command will be failed with -EINVAL status by saying that this buffer is already registered by the application. When user issues a trace buffer register command through sysfs parameter, and if trace buffer is in released stated but not yet unregistered by the application which was owning it, then driver will unregister the buffer by itself and freshly register the 1MB sized trace buffer with the HBA firmware.

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.
