From 450d06c0208ad195ccd74a7edd11321e316791ad Mon Sep 17 00:00:00 2001 From: Sherman Pun Date: Thu, 11 Mar 2010 13:50:05 +0000 Subject: [PATCH] RDS: Properly unmap when getting a remote access error If the RDMA op has aborted with a remote access error, in addition to what we already do (tell userspace it has completed with an error) also unmap it and put() the rm. Otherwise, hangs may occur on arches that track maps and will not exit without proper cleanup. Signed-off-by: Andy Grover Signed-off-by: David S.
