From 1d2e3f396c532b95a37bbee92269f37efe908457 Mon Sep 17 00:00:00 2001 From: "santosh.shilimkar@oracle.com" Date: Sat, 22 Aug 2015 15:45:22 -0700 Subject: RDS: restore return value in rds_cmsg_rdma_args() In rds_cmsg_rdma_args() 'ret' is used by rds_pin_pages() which returns number of pinned pages on success. And the same value is returned to the caller of rds_cmsg_rdma_args() on success which is not intended. Commit f4a3fc03c1d7 ("RDS: Clean up error handling in rds_cmsg_rdma_args") removed the 'ret = 0' line which broke RDS RDMA mode. Fix it by restoring the return value on rds_pin_pages() success keeping the clean-up in place. Signed-off-by: Santosh Shilimkar Signed-off-by: Santosh Shilimkar Signed-off-by: David S.
