I just went ahead and backed out the problematic change. Haven't even

fixes it.
Hi Kent,
I pull down your latest code and did a build. I'm pleased to say
that Windows has now installed. I will do some further
testing/benchmarking to make sure that the install is stable.
Many thanks for your quick help
Hi Kent,
A little bad news. With this new build, the spindles are getting
thrashed and this is constantly (never stopping) spewing out on my
netconsole:

Any ideas?
Oh hell, I see the problem. That one is not going to be such an easy
fix. I'm going to have to think about it.
Amusing part is it looks like blocksize = 4k was working around the
problem... :/
Ah, ok :)
Please keep me posted when this is fixed, I'm very keen to see
bcache deployed in our cloud infrastructure :)
If there is anything I can do to help from a testing standpoint,
please let me know.
I had an idea for how to work around it :) (and other potential issues
I recently became aware of).
More untested code up!
Wow that was quick! I'll send this to the build server and let you know
the results.
Cheers
Jonny
