You're welcome.

Yes, I'll submit a pull-up request shortly for both branches.

I would have thought that a raid 5 set would actually hide the
I/O error from the ld layer.  If I've not misunderstood
completely, the whole point of raid5 is to be able to continue
operation with one component which has failed.  In other words, I
would not have expected an IO error from ld0 or fsbn errors from
the file system in this case.

Sorry, I'll have to say "pass" on these; you require comments
from someone familiar with the hardware and the innards of the
driver, and that isn't me...
