Hi all,

I am looking for the vestiges of the /dev/io implementation in the 1.6.1 
kernel source tree. I cannot seem to find it, and it is not built (the 
manpage says it is built when OPTION_10 is defined but that options 
is defined in GENERIC and other kernels and /dev/io isn't built).

So, my question is: what version is known to have a working /dev/io 
built in it. I would like to look at the code for inspiration.

thanks,
Peter
