I am currently working on my master's thesis trying to increase
number of merges of VMAs currently failing because of page offset
incompatibility and difference in their anon_vmas. The following
refactor and added merge call included in this series is just two
smaller upgrades I created along the way.

The rest of the work is still being worked on but was send to mailing
list as a RFC:
https://lore.kernel.org/all/20220516125405.1675-1-matenajakub@gmail.com/

This patch series is based on tag v5.18-rc2.
