This revision was automatically updated to reflect the committed changes.

This is now merged, however:

I like to style the functions in a way that you only have one return at the end, or a few for parameter checking in the beginning

I like to keep it that way since this lowers the risk of someone adding code to the end of the function, and later recognizing that this code is never executed, since one tiny codepath calls return ...

Please take this to note for further patches, thx! :)

Yeah I thought about commenting "why not else if (manager) instead?"... :)

agree. i think else if (manager) is better :)

btw, when v is true, we don't need to check whether registered_manager already assigned?
