Alan,
Thanks for the prompt response. I am merging the Dolphin SCI High Speed interconnect drivers into 2.2.18 and 2.4.0 for our M2FS project, and I am reviewing the big ugly nasty patch they have current as of 2.2.13 (really old). I will be looking over the 2.4 tree for a more clean manner to do what they want.
What's in the patch alters the /proc filesystem, and the VM code. I will submit a patch against 2.2.19 and 2.4.0 for this support for their SCI adapters after I get a handle on it.
:-)
