The locking order currently requires the alloc->mutex to be acquired first followed by the mmap lock. However, the alloc->mutex is converted into a spinlock in subsequent commits so the order needs to be reversed to avoid nesting the sleeping mmap lock under the spinlock. The shrinker's callback binder_alloc_free_page() is the only place that needs to be reordered since other functions have been refactored and no longer nest these locks. Some minor cosmetic changes are also included in this patch.

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.
