Guess what happens if you try to git revert a merge? Yeah. Don’t do that.
You can, but you really need to understand what happens when you do so, so that you're not confused by future merges from the same branch. Straight from the horse's mouth:
https://www.kernel.org/pub/software/scm/git/docs/howto/rever...
Like if you created a new branch from master and you have been merging master into your branch to get updates in master, once you merge your branch into master you cannot revert this merge because the act of merging master into your branch changed which branch owned commits.
If you rebased master into your branch instead everything will be fine. If you merge your branch into master, reverting that merge will simply undo the merge as you expected.
TIMTOWTDI.
