Thoughts?
Since the ucma will not make it for the 2.6.19 feature merge window, why not target both the ucma and the cma ud/ud-mulitast support for 2.6.20? This way you would be doing one big ABI change and would not carry this HUGE svn/git diff. As I have mentioned in the other thread, once it would make sense from your schedule to do the patch preparation work, it would be good to push it into the for-2.6.20 branch of Roland's tree from where it can go to the -mm tree so people can start testing it. Once the code is in the for-2.6.20 branch, it would be also possible to include it in OFED 1.2 release which is expected on December this year.
