Per your request we provided the information on tests conducted with
the patches.
Note that the patches can't really disrupt existing applications that
don't set the new IB_ACCESS_ON_DEMAND MR flag when they register
memory. Also the whole set of changes to the umem area is dependent on building with
CONFIG_INFINIBAND_ON_DEMAND_PAGING -- all in all, everything is in
place for protecting against potential regression that this series
could introduce.
As you didn't provide any feedback for > six months, and we have all
the above in place (report on stability tests, performance data and
mechanics to avoid regressions) I think it would be fair to get this
picked for the coming merge window, thoughts?
