If anyone has any objections, please let me know. ------------------ From: Ka-Cheong Poon 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().
