I really really want a nommu UML mode for testing purposes so I'm very happy you're doing this :) One mildly annoying note though - it'd be good for the cover letter to summarise what the series is about, what it achieves, how it compares for instance to Hajime's original approach ([0]). I guess how cover letters are used varies by subsystem somewhat but I find it really actively useful to see a summary in the cover letter. Anyway reading thorugh the RFC which already covers this seems that this achieves nommu UML with less changes needed which sounds really interesting! I may pull this series locally and have a play... :) > > I cleaned up and added the docs commit now, other changes: > - fixed futex implementation after discussions > - fixed regression in earlier uname change > > johannes > Cheers, Lorenzo [0]:https://lore.kernel.org/all/m2framxerm.wl-thehajime@gmail.com/
