Now that we clearly only care about the length of the name we just parsed, we can simplify and clarify the interface to "name_hash()", and move the actual nd->last field setting in there. That makes everything simpler, and this way don't mix the hash and the length together only to then immediately unmix them again. We still eventually want the combined mixed "hashlen" for when we look things up in the dentry cache, but inside link_path_walk() it's simpler and clearer to just deal with the path component length.

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.
