From: Moni Shoua Date: Mon, 25 Feb 2019 06:53:00 +0000 (+0200) Subject: IB/mlx5: Set correct write permissions for implicit ODP MR X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=7095ec3ca00eba04553d4c323dc9dd160219dd68;p=linux.git IB/mlx5: Set correct write permissions for implicit ODP MR The write access of an implicit MR is inherited to all of its children. Therefore we must set the correct write access to the parent MR. Pass full access_flags when creating umem to let it calculate write access correctly.
