If we enable_breadcrumbs for a request while that request is being removed from HW; we may see that the request is active as we take the ce->signal_lock and proceed to attach the request to ce->signals. However, during unsubmission after marking the request as inactive, we see that the request has not yet been added to ce->signals and so skip the removal. Pull the check during cancel_breadcrumbs under the same spinlock as enabling so that we the two tests are consistent in enable/cancel. Otherwise, we may insert a request onto ce->signals that we expect should not be there: intel_context_remove_breadcrumbs:488 GEM_BUG_ON(!__i915_request_is_complete(rq)) While updating, we can note that we are always called with irqs-disabled, due to the engine->active.lock being held at the single caller, and so remove the irqsave/restore making it symmetric to enable_breadcrumbs.

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.
