By now there is only one place in entire fast_dput() where we return false; that happens after refcount had been decremented and found (under ->d_lock) to be zero. In that case, just prior to returning false to caller, fast_dput() forcibly changes the refcount from 0 to 1. Lift that resetting refcount to 1 into the callers; later in the series it will be massaged out of existence.

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.
