There are several sanity checks and recover handling if they occur in the dlm plock handling. From my understanding those operation can't run in parallel with any list manipulation which involved setting the list holder of plock_op, if so we have a bug which this sanity check will warn about. Previously if such sanity check occurred the dlm plock handling was trying to recover from it by deleting the plock_op from a list which the holder was set to. However there is a bug in the dlm plock handling if this case ever happens. To make such bugs are more visible for further investigations we add a WARN_ON() on those sanity checks and remove the recovering handling because other possible side effects.

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.
