Hi This is the 3rd version of multifd. Changes: - comments for previous verion addressed - lots of bugs fixed - remove DPRINTF from ram.c
- add multifd-group parameter, it gives how many pages we sent each time to the worker threads. I am open to better names. - Better flush support. - with migration_set_speed 2G it is able to migrate "stress -vm 2 -vm-bytes 512M" over loopback. Please review. Thanks, Juan. [v2] This is a version against current code. It is based on top of QIO work. It improves the thread synchronization and fixes the problem when we could have two threads handing the same page. Please comment, Juan.
