I have a plan to write a quick test to exercise concurrent usage of i915_gem_shrink(), the simplest way looks to be to have multiple threads using debugfs/i915_drop_caches. However, we currently take one lock over the entire function, serialising the calls into i915_gem_shrink() so reduce the lock coverage.
