[PATCH 0/3] quorum: Require WRITE perm with rewrite-corrupted |

Hi,
While reviewing Berto’s block-status/write-zeroes series for quorum, I
wondered how quorum’s permission code handles rewrite-corrupted. It
turns out it doesn’t, and so qemu with a read-only rewrite-corrupted
quorum node simply crashes once there is a mismatch that leads to a
rewrite.
It looks to me like this bug has existed for quite some time, so I don’t
think this series must go into 5.2. OTOH, it’s a simple bug fix, so I
suppose it might as well.
