See http://www.infradead.org/rpr.html Precedence: bulk List-ID: X-Mailing-List: linux-block@vger.kernel.org Hi Jens, this series resurrects a patch from Martin to properly split the flag indicating a disk has been set read-only by the hardware vs the userspace policy set through the BLKROSET ioctl. This series is based on top of the "merge struct block_device and struct hd_struct v4" series and won't apply to mainline or Jens' for-5.11 tree. A git tree is available here: git://git.infradead.org/users/hch/block.git block-hard-ro Gitweb: http://git.infradead.org/users/hch/block.git/shortlog/refs/heads/block-hard-ro Changes since v1: - don't propagate the policy flag from the whole disk to partitions - rebased on top of the merge block_device and hd_struct series
