commit 77bc4d4921bd3497678ba8e7f4e480de35692f05 upstream. The creation of the top events directory does a dget() at the end of the creation in eventfs_create_events_dir() with a comment saying the final dput() will happen when it is removed. The problem is that a dget() is already done on the dentry when it was created with tracefs_start_creating()! The dget() now just causes a memory leak of that dentry. Remove the extra dget() as the final dput() in the deletion of the events directory actually matches the one in tracefs_start_creating().

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.
