From 840df162b3eb3ec02e2613411fad1285a0017c13 Mon Sep 17 00:00:00 2001 From: Sowmini Varadhan Date: Wed, 2 Aug 2017 10:34:31 -0700 Subject: rds: reduce memory footprint for RDS when transport is RDMA RDS over IB does not use multipath RDS, so the array of additional rds_conn_path structures is always superfluous in this case. Reduce the memory footprint of the rds module by making this a dynamic allocation predicated on whether the transport is mp_capable.
