This patch adds a CONFIG_DLM_DEPRECATED_API Kconfig option that must be enabled to use two timeout-related features that we intend to remove in kernel v6.2. Warnings are printed if either is enabled and used. Neither has ever been used as far as we know. . The DLM_LSFL_TIMEWARN lockspace creation flag will be removed, along with the associated configfs entry for setting the timeout. Setting the flag and configfs file would cause dlm to track how long locks were waiting for reply messages. After a timeout, a kernel message would be logged, and a netlink message would be sent to userspace. Recently, midcomms messages have been added that produce much better logging about actual problems with messages. No use has ever been found for the netlink messages. . The userspace libdlm API has allowed the DLM_LKF_TIMEOUT flag with a timeout value to be set in lock requests. The lock request would be cancelled after the timeout.

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.
