Getting an obscure driver into mainline

Getting an obscure driver into mainline

[Kieran Kunhya]

Hello,

I have reverse engineered a driver for Sony SxS memory cards which are
expresscards used in professional cameras. Unfortunately I haven't
figured out how to make it work with DMA as used in the block device
API; currently it only works with a memcpy. I'm not really sure if I'm
using the block device API incorrectly and was told to ask here (and
cc GKH) since I didn't hear much from lkml.

My code is here: https://github.com/kierank/sxs-linux

What is the next step for getting this into mailing and who is the
person to ask about block device DMA?

Kieran

I'd turn it into a patch for the drivers/block/ directory and submit it
to the people that scripts/get_maintainer.pl says to use.  Also cc: the
linux-fsdevel mailing list as the developers there might be able to help
out on the block dma issues.

I can always put it in the drivers/staging/ directory today, but I don't
see any reason it shouldn't just go into the main part of the kernel
instead.

Hope this helps,
