Well I can kind of see what this is doing - it increases the amount of info in /proc/vmallocinfo for regions which were created by vm_map_area(), yes?
But I'd like to hear it in your words, please. What problem are we trying to solve? Why is it actually a problem? Why is the additional information considered useful, etc?
It would help a lot if the changelog were to include before-and-after examples from the /proc/vmallocinfo output.
Thanks.
