Why restructure the failure path ?
Daniel
It is a trivial change of replacing a goto with an assignment and moving
it a few lines down. It reduces "jumpiness" within that function and is
a cleaner version. On the more practical side, it was done in
preparation for some other changes I have coming up, which touch that
function and work a lot better with the cleaned-up failure path. The
next patch was delayed (due to a dependency) but as long as I was doing
code cleanup, I saw no reason not to also clean up the failure path as
part of this series.
