When a process cannot be oom reaped, for whatever reason, currently the list of locks that are held is currently dumped to the kernel log. Much more interesting is the stack trace of the victim that cannot be reaped. If the stack trace is dumped, we have the ability to find related occurrences in the same kernel code and hopefully solve the issue that is making it wedged. Dump the stack trace when a process fails to be oom reaped.

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.
