If the shrinker returns sc->nr_scanned==0 then that's a buggy shrinker - it should return SHRINK_STOP in that case. Only a single shrinker (i915) presently uses sc->nr_scanned and that one gets it right. I think it's OK - there's a limit to how far we should go defending against buggy kernel code, surely. _______________________________________________ Intel-gfx mailing list Intel-gfx@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/intel-gfx
