Yes, I'm doing a fair bit.
If you are interested in the "md" driver, you really should join
linux-raid@vger.kernel.org
With reguard to your patch, the short answer is that you really don't
want to do that (or atleast, I don't want to, and I think that you
should agree with me:-)
autorun/autodetect just doesn't belong in the kernel. It should be
done in user space. The only time the kernel should assemble a raid
array itself is for the root device, and this is best done with
md=0,/dev/whatever,etc
If I could start with a clean slate, I would rip out the autodetect
stuff completely. But lots of people are depending on it so I cannot.
It is true that there is not currently any userlevel tool which does
the equivalent of autodetect, but there will be soon. It has been
mentioned on linux-raid and an announcement will go there when it is
ready for wider testing.
