git log -L:function_name:file_name can be used to get the log of all commits that touched a specific function. But it always shows the content/diff of the commit as if -p option was applied.

I have tried to several different options to the command like --oneline, --abbrev-commit, -U0 but they just remove a few lines and still print a lot of commit content.

How can I get a oneline summary?
