Linux kernel source tree
75404e0766
Currently the VMA and mmap locking logic is entangled in two of the most overwrought files in mm - include/linux/mm.h and mm/memory.c. Separate this logic out so we can more easily make changes and create an appropriate MAINTAINERS entry that spans only the logic relating to locking. This should have no functional change. Care is taken to avoid dependency loops, we must regrettably keep release_fault_lock() and assert_fault_locked() in mm.h as a result due to the dependence on the vm_fault type. Additionally we must declare rcuwait_wake_up() manually to avoid a dependency cycle on linux/rcuwait.h. Additionally move the nommu implementatino of lock_mm_and_find_vma() to mmap_lock.c so everything lock-related is in one place.

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.
