Similar to for i915_active.mutex, we require each class of i915_active to have distinct lockdep chains as some, but by no means all, i915_active are used within the shrinker and so have much more severe usage constraints. By using a lockclass local to i915_active_init() all i915_active workers have the same lock class, and we may generate false positives when waiting for the i915_active. If we push the lockclass into the caller, each class of i915_active will have distinct lockdep chains.

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.
