Log flush operations (gfs2_log_flush()) can target a specific transaction. But if the function encounters errors (e.g. io errors) and withdraws, the transaction was only freed it if was queued to one of the ail lists. If the withdraw occurred before the transaction was queued to the ail1 list, function ail_drain never freed it. The result was: BUG gfs2_trans: Objects remaining in gfs2_trans on __kmem_cache_shutdown() This patch makes log_flush() add the targeted transaction to the ail1 list so that function ail_drain() will find and free it properly.

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.
