If buddy manager have more than one roots and each root have sub-block need to be free. When drm_buddy_fini called, the first loop of force_merge will merge and free all of the sub block of first root, which offset is 0x0 and size is biggest(more than have of the mm size). In subsequent force_merge rounds, if we use 0 as start and use remaining mm size as end, the block of other roots will be skipped in __force_merge function. It will cause the other roots can not be freed. Solution: use roots' offset as the start could fix this issue.

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 reStructuredText 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.
