[ Upstream commit 8f1752723019db900fb60a5b9d0dfd3a2bdea36c ]
In smb2_lock(), if setup_async_work() executes successfully,
work->cancel_argv will bind the argv that generated by kmalloc(). And
release_async_work() is called in ksmbd_conn_try_dequeue_request() or
smb2_lock() to release argv.
However, when setup_async_work function fails, work->cancel_argv has not
been bound to the argv, resulting in the previously allocated argv not
being released. Call kfree() to fix it.

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.
