commit a45e6889575c2067d3c0212b6bc1022891e65b91 upstream. Unlike early commit path stage which triggers a call to abort, an explicit release of the batch is required on abort, otherwise mutex is released and commit_list remains in place. Add WARN_ON_ONCE to ensure commit_list is empty from the abort path before releasing the mutex. After this patch, commit_list is always assumed to be empty before grabbing the mutex, therefore03c1f1ef15("netfilter: Cleanup nft_net->module_list from nf_tables_exit_net()") only needs to release the pending modules for registration.

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.
