The logic to free the eventfs_inode (ei) use to set is_freed and clear the "dentry" field under the eventfs_mutex. But that changed when a race was found where the ei->dentry needed to be cleared when the last dput() was called on it. But there was still logic that checked if ei->dentry was not NULL and is_freed is set, and would warn if it was. But since that situation was changed and the ei->dentry isn't cleared until the last dput() is called on it while the ei->is_freed is set, do not test for that condition anymore, and change the comments to reflect that.

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.
