I think you had 12K requests of 1 block each, in each of 6 devices.
That's 70K requests, 4K each, that's 280MB. OK, there's no way one can
lose more than one's seen, so this is something else. Maybe the driver
is just "too big"?

Can you observe the growth with time or requests of this figure?

I can take out the statics in the driver and put them under kmalloc
control.  I have a patch for that.  I did it to the 2.4 driver and it
cut the apparent size in half (from 100K+ to 50K).
