commit a9de4eb15ad430fe45747c211e367da745a90093 upstream. As the comment right above a WARN_ON() in create_file_dentry() states: * Note, with the mutex held, the e_dentry cannot have content * and the ei->is_freed be true at the same time. But the WARN_ON() only has: WARN_ON_ONCE(ei->is_free); Where to match the comment (and what it should actually do) is: dentry = *e_dentry; WARN_ON_ONCE(dentry && ei->is_free) Also in that case, set dentry to NULL (although it should never happen).

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.
