4.9-stable review patch. If anyone has any objections, please let me know.
------------------ From: Tejun Heo <[email protected]> commit ebc4ff661fbe76781c6b16dfb7b754a5d5073f8e upstream. cfq_cpd_alloc() which is the cpd_alloc_fn implementation for cfq was incorrectly hard coding GFP_KERNEL instead of using the mask specified through the @gfp parameter. This currently doesn't cause any actual issues because all current callers specify GFP_KERNEL. Fix it.
