The btrfs_transaction struct leaks, which can cause sporadic fstests
failures when kmemleak checking is enabled:
kmemleak: 5 new suspected memory leaks (see /sys/kernel/debug/kmemleak)

unreferenced object 0xffff88810fdc6c00 (size 512):

The transaction struct was initially stack-allocated but switched to
heap following frame size compiler warnings.

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 reStructuredText 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.
