Subject: [PATCH, RFC 11/10] block: propagate BLKROSET to all partitions
Date: Fri, 6 Nov 2020 15:08:17 +0100	[thread overview]
Message-ID: <20201106140817.GA23557@lst.de> (raw)


When setting the whole device read-only (or clearing the read-only
state), also update the policy for all partitions.  The s390 dasd
driver has awlways been doing this and it makes a lot of sense.
