Subject: remove DMA_ATTR_WRITE_BARRIER
Date: Wed, 13 Nov 2019 08:32:12 +0100 [thread overview]
Message-ID: <20191113073214.9514-1-hch@lst.de> (raw)
There is no implementation of the DMA_ATTR_WRITE_BARRIER flag left
now that the ia64 sn2 code has been removed. Drop the flag and
the calling convention to set it in the RDMA code.
