commit2b575eb64f("mm: convert anon_vma->lock to a mutex") changed spinlock used to serialize access to vma list to mutex. And further, the commit5a505085f0("mm/rmap: Convert the struct anon_vma::mutex to an rwsem") converted the mutex to an rwsem for solving scalability problem. So replace spinlock with rwsem to make comment uptodate.

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.
