For this one, I'm not sure If I can take it yet. The changes you added if for are not merged, therefore merging this looks bad from process point of view (I'm merging feature that is not available in kernel upstream). Am I missing something? I would like to hear Song voice on that. IMO, you should keep it as your own customization until development of new bitmap is done but I understand that the topic is not simple and you might want to people to test it so having mdadm build-in is an option. If you really want this I would need a detailed process of "way to stable" in commit message that I can always refer to. I'm challenging something like that first time so I hope Song can add something. Thanks, Mariusz
