1) lift NUL-termination into the callers 2) pass pointer to the end of buffer instead of that to beginning. (1) allows to simplify dentry_path() - we don't need to play silly games with restoring the leading / of "//deleted" after __dentry_path() would've overwritten it with NUL. We also do not need to check if (either) prepend() in there fails - if the buffer is not large enough, we'll end with negative buflen after prepend() and __dentry_path() will return the right value (ERR_PTR(-ENAMETOOLONG)) just fine.

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.
