Subject: split hard read-only vs read-only policy v2
Date: Sun, 29 Nov 2020 19:19:22 +0100 [thread overview]
Message-ID: <20201129181926.897775-1-hch@lst.de> (raw)
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
