Patch series "Anon rmap cleanups". Some cleanups around rmap for anon pages. I'm working on more cleanups also around file rmap -- also to handle the "compound" parameter internally only and to let hugetlb use page_add_file_rmap(), but these changes make sense separately. This patch (of 6): That comment was added in commit5dbe0af47f("mm: fix kernel BUG at mm/rmap.c:1017!") to document why we can see vma->vm_end getting adjusted concurrently due to a VMA split. However, the optimized locking code was changed again inbf181b9f9d("mm anon rmap: replace same_anon_vma linked list with an interval tree."). ... and later, the comment was changed in commit0503ea8f5b("mm/mmap: remove __vma_adjust()") to talk about "vma_merge" although the original issue was with VMA splitting. Let's just remove that comment. Nowadays, it's outdated, imprecise and confusing.

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.
