It is possible to ignore the validation for a certain lock by using: lockdep_set_novalidate_class() on it. Each invocation will assign a new name to the class it created for created __lockdep_no_validate__. That means that once lockdep_set_novalidate_class() has been used on two locks then class->name won't match lock->name for the first lock triggering the warning. So ignore changed non-matching ->name pointer for the special __lockdep_no_validate__ class.

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.
