The waiters_mutex no longer needs to be used in the waiters recovery functions dlm_recover_waiters_pre() and dlm_recover_waiters_pre(). During recovery, ordinary locking operations are paused, and the recovery thread is the only context accessing the waiters list, so the lock is not needed. Access to the waiters list from debugfs functions is avoided by taking the top level recovery lock in the debugfs dump function.

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.
