The test cases are based on the man > page available at http://linux.die.net/man/2/move_pages Thank you very much for quickly posting your design. I would loop in few more people i know who are also trying to write some similar test cases on move_pages, for better understanding, and for the sake that both your ´s and their work can be mutually beneficial. Nagesh/Supriya, Can you please look in to this design aspects of Vijay. I would like to propose few things here: 1) Nagesh/Supriya, please provide review comments to Vijay on his design, 2) Vijay can go ahead in writing those tests that he has proposed. You can review his patches then, 3) You can propose what additional tests needs to be done. And you can write those additional tests. With this we can perhaps avoid duplication of effort. What do you say ? I also found a sample test case for move_pages() on the net: https://gforge.inria.fr/plugins/scmsvn/viewcvs.php/trunk/marcel/examples/nouma/simple/test_move_pages.c?rev=18613&root=pm2&view=markup, Regards-- Subrata > > BTW, I am planning to do the testing using numa=fake, hope > that should suffice. > > Test 1: Test retrieval of NUMA node > > 1.
