The file uses a mixture of tabs and spaces. In this case I used tabs, the bullet point above uses spaces, that's why it looks kind of off in the patch. Otherwise I used the same indentation as some other bullet points so I don't think there is anything to fix in this patch. > > With that fixed: > Reviewed-by: Darrick J.
