The simple_map_init() works at a higher level, what I'm redefining is a
function called by mtd->read()
The block size for e.g. a dd if=/dev/mtd0 of=/dev/null
with the default block size (I believe it's 512Bytes), fetches from
/dev/mtd0 4096 Bytes at a time.
I'd prefer the kernel to be scheduling other tasks meanwhile, instead of
busy-waiting on completion.

Remove the call to simple_map_init() and do it manually in your driver
with your own functions.
And yes, as soon as I've cleaned up the code a little bit, I will
definitely post a patch about it.
Moreover: a huge benefit would come from exploiting DMA on these
transfers,
probably depends on the block size if it's a gain or not. What is the
size you normally see.
