Adding a non-blocking erase func

[Derek Ross]

Hello,

Say I wanted to write another erase function
that's ioctl callable. This function would 
be non-blocking.

Would it be good to:

1. add another define "MEMERASE_NDELAY,"

2. Go into the function mtd_ioctl, and
add a case for MEMERASE_NDELAY.

3. The case for MEMERASE_NDELAY
would be a copy of MEMERASE except with the 
wait_queue stuff taken out.

Would this be a simple task (in your opinion)
or would that be one of those things that
would be tricky to debug and get working?

Thanks, 
Derek.
