Have you find a proper solution for this very issue or anything that can push forward addressing it? Thankfully this issue has been addressed by a workaround in fs/dcache.c in grsecurity patch for 3.16.2 (grsecurity-3.0-3.16.2-201409082129.patch) but it would be great to have a fix upstream. -- Piotr.
