[ Upstream commit 12f47bf0f0990933d95d021d13d31bda010648fd ] FAN_FS_ERROR doesn't support DFID, but this function is still called for every event. The problem is that it is not capable of handling null inodes, which now can happen in case of superblock error events. For this case, just returning dir will be enough.

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.
