git-deps shows unrelated commits when dependency of 'merge' commits are checked

I'm using the git-deps tool for linux kernel backporting work.

When git-deps is run to find any dependent commits in linux kernel there is a chance it encounters 'merge' commits. git-deps output is very huge when it checks dependency for 'merge' commits and git-deps needs to be stopped manually since it runs for a very long time.

Maybe '--no-merges' needs to be used to avoid merge commits?

Start by reproducing the report with git-deps on a history containing merge commits, using the Linux kernel backporting scenario described. Trace the dependency output for a merge commit and compare it with the expected relevant commits; it is done when unrelated commits are excluded and the command completes without needing manual interruption.
