Eventfs uses simple_lookup(), however, it will fail if the name of the entry is beyond NAME_MAX length. When this error is encountered, eventfs still tries to create dentries instead of skipping the dentry creation. When the dentry is attempted to be created in this state d_wait_lookup() will loop forever, waiting for the lookup to be removed. Fix eventfs to return the error in simple_lookup() back to the caller instead of continuing to try to create the dentry.

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.
