I don't think so -- in fact, it could be the best candidate for

you could also send this to the stable maintainers?).
But I do want to have this fixed in a "nice" way. eg. I'd like
it to mark the buffers dirty because that actually results in
more reuse of generic kernel code, and also should make rd
behave more naturally (I like using it to test filesystems
because it can expose a lot more concurrency than something like
loop on tmpfs). It should also be possible to actually have
rd's buffer heads get reclaimed as well, preferably while
exercising the common buffer paths and without writing much new
code.
All of that is secondary to fixing the data corruption problem
of course! But the fact that those alternate patches do exist now
means I want to just bring them into the discussion again before
merging one or the other.
