Casey, I think you haven't applied this one.

Subject: [PATCH] Smack: Use GFP_KERNEL for smk_netlbl_mls().
Date: Mon, 14 Nov 2016 20:12:56 +0900

Since all callers of smk_netlbl_mls() are GFP_KERNEL context
(smk_set_cipso() calls memdup_user_nul(), init_smk_fs() calls
__kernfs_new_node(), smk_import_entry() calls kzalloc(GFP_KERNEL)),
it is safe to use GFP_KERNEL from netlbl_catmap_setbit().
