One more question,
I currently prefix the names with "bdi-", is that needed?
That is, if I give the bdi object a parent, how will it look?
Would a bdi device with name "sda" with a block device called "sda" as
parent look like: /sys/block/sda/sda? Or would if be
called /sys/block/sda/bdi:sda or j

Hi,
Thanks for the help so far, however we're still not quite there.
The below patch still has the funny 20 character name limit. Is there a
good reason its a char array like this, and not just a char * to a kstr?
The code does kstrdup all over the place, I can't imagine why suddenly
limiting it

Ok, can't sleep.. took a look. I have several problems here.

This crashes and burns on bootup, but I'm too tired to figure out what I
