Mainline Linux tree for various devices, only for fun :)
64094a0441
XArray has friendly APIs and it will replace the old radix tree in the near future. This convert makes use of __xa_cmpxchg when inserting on a just inserted item by other thread. In detail, instead of totally looking up again as what we did for the old radix tree, it will try to legitimize the current in-tree item in the XArray therefore more effective. In addition, naming is rather a challenge for non-English speaker like me. The basic idea of workstn is to provide a runtime sparse array with items arranged in the physical block number order. Such items (was called workgroup) can be used to record compress clusters or for later new features. However, both workgroup and workstn seem not good names from whatever point of view, so I'd like to rename them as pslot and managed_pslots to stand for physical slots. This patch handles the second as a part of the radix tree convert.

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.
