[Intel-gfx] [PATCH] drm/i915/gt: Drop active.lock around active request read inside execlists

[Intel-gfx] [PATCH] drm/i915/gt: Drop active.lock around active request read inside execlists

[Chris Wilson]

As we find the active request for capturing upon a hang, we know that the
lists are stable as we are inside the execlists tasklet, the only path
that can modify those lists. As such, we do not need to disable irqs and
take the active lock for a simple read of the current request.
