new helper: choose_mountpoint(). Wrapper around choose_mountpoint_rcu(), similar to lookup_mnt() vs. __lookup_mnt(). follow_dotdot() switched to it. Now we don't grab mount_lock exclusive anymore; note that the primitive used non-RCU mount traversals in other direction (lookup_mnt()) doesn't bother with that either - it uses mount_lock seqcount instead.

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.
