Hello, 1/3 is a bugfix and it fixes userland (not kernel) data corruption with vfio (and in general device driver) page pinning done with get_user_pages. More testing of it under any load is welcome (also not necessarily a page pinning load using vfio). Along with the above I'm sending also 2/3 and 3/3 but those are not meant to be merged upstream quickly and they're very low priority and furthermore 2/3 is not zero risk and it didn't get enough testing yet. Queuing 2/3 in -mm to give it more exposure should be ok though. 2/3 is only suitable for merging at the very opening of merge window anyway.
