I know the names are not correct, but they are in the style of existing node
names in the same file. Do you want me to change them all, or just this one?
This change would break existing user-space software though, which is something
I prefer not to do. Unfortunately both names are relied upon by user-space
software for almost 10 years now, and changing them will force me to maintain
off-tree patches that revert these changes.
I understand the reason for the change though, and if you insist I will do it.

Best regards,
