The above sentence is the most important part of the patchset. Because it answers the question "ytf is Haggai sending this stuff at me". I'm unsure if the patchset adds runtime overhead but it does add maintenance overhead (perhaps we can reduce this - see later emails). So we need to take a close look at what we're getting in return for that overhead, please. Exactly why do we want on-demand paging for Infiniband? Why should anyone care? What problems are users currently experiencing? How many users and how serious are the problems and what if any workarounds are available? Is there any prospect that any other subsystems will utilise these infrastructural changes? If so, which and how, etc?
