From 251bc1f44c33a8707d9bd0a1eef459224ab5da99 Mon Sep 17 00:00:00 2001 From: Ka-Cheong Poon Date: Mon, 30 Jul 2018 22:48:41 -0700 Subject: [PATCH] rds: rds_ib_recv_alloc_cache() should call alloc_percpu_gfp() instead MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit commit f394ad28feffbeebab77c8bf9a203bd49b957c9a upstream. Currently, rds_ib_conn_alloc() calls rds_ib_recv_alloc_caches() without passing along the gfp_t flag. But rds_ib_recv_alloc_caches() and rds_ib_recv_alloc_cache() should take a gfp_t parameter so that rds_ib_recv_alloc_cache() can call alloc_percpu_gfp() using the correct flag instead of calling alloc_percpu().
