  "message": "drm/i915/ttm: Fix illegal addition to shrinker list\n\nThere\u0027s a small window of opportunity during which the adjust_lru()\nfunction can be called with a GEM refcount of zero from the TTM\neviction code. This results in a kernel BUG().\n\nEnsure that we don\u0027t attempt to modify the GEM shrinker lists unless\nwe have a GEM refcount.\n\nFixes: ebd4a8ec7799 (\"drm/i915/ttm: move shrinker management into adjust_lru\")\nSigned-off-by: Thomas Hellström \u003cthomas.hellstrom@linux.intel.com\u003e\nReviewed-by: Matthew Auld \u003cmatthew.auld@intel.com\u003e\nLink: https://patchwork.freedesktop.org/patch/msgid/20211110085527.1033475-1-thomas.hellstrom@linux.intel.com\n",
