Subject: [PATCH rdma-core] fix udma_to_device_barrier on aarch64
Date: Wed, 22 Mar 2017 22:12:24 -0400 [thread overview]
Message-ID: <20170323021224.35722-1-jarod@redhat.com> (raw)
The definition for udma_to_device_barrier on aarch64 is missing. Looks
like an oversight in the commit that removed the old barrier macros and
added this one.
Fixes: 85a5529dead5 ("Remove the old barrier macros")
