Your code has been kept out of the main kernel for a year or so?  Sigh. 
 I guess 2.4 has been freezing (except for VFS and MM which I will say

Chris and Edward, can you look at it and create a complementary patch to 
make use of it that we can ask Andre to add to his patch, and then link 
to his patch on our website?
