Refer to commit > 9b9879fc03275ff ("modules: catch concurrent module loads, treat them as > idempotent") for details. Thanks, that helps a lot. Given that this commit landed in v6.5 I guess there's not really a concern to force enable FW_CACHE for Nouveau as a fix for commit 176fdcbddfd2 ("drm/nouveau/gsp/r535: add support for booting GSP-RM"), which landed in v6.7.
