I would suggest that you use merge sort.  It is ideally suited for sorting
linked lists, and it always has N log N running time.  I dont know of an
existing implementation in the kernel sources, but it should be easy to
write one.  I did a google search on "merge sort" "linked list" and it
comes up with lots of links.  Here is a good one:

Hope this helps,

Jim
