Some devices come online in write protected state and switch to read-write once they are ready to process I/O requests.
That is really weird. What kind of devices are these?
Note that per-partition ro settings are lost on revalidate. This has been broken for at least a decade and it will require major surgery to fix. To my knowledge nobody has complained about being unable to make partition read-only settings stick through a revalidate. So hopefully this patch will suffice as a simple fix for stable.
Should we warn when we lost these settings on a revalidate?
I have to say I don't like the tristate too much - it seems to allow setting a hardware write protected device writable again by user interfaction, right?
Should we just have a hardware and a user policy field that are separate instead?
