 Hi,
   I am looking for best way of understanding MD
driver(including raid5/6) architecture. I am
developing driver for one of the PPC based SOC. I have
done some code reading and tried to use HW debugger to
walk through the code. But it was not much help.

  If you have any pointers or documents, I will
greatly appreciate if you can share it.

I started out with include/linux/raid/raid5.h.  Also, running it with
the debug print statements turned on will get you familiar with the
code flow.

Lastly, I wrote the following paper which is already becoming outdated:

Thanks and regards,
