Jeff Layton bd6aaf781d nfsd: fix potential race in nfs4_find_file

The WARN_ON_ONCE check is not terribly useful. It also seems possible
for nfs4_find_file to race with the destruction of an fi_deleg_file
while trying to take a reference to it.

Now that it's safe to pass nfs_get_file a NULL pointer, remove the WARN
and NULL pointer check. Take the fi_lock when fetching fi_deleg_file.

README

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.
