It's wrong. We had a lengthy analysis of this piece of code
several months ago, and it is correct.
Consider, if we run the loop and we get an error
the following happens:
1) attempt of ifb_init_one(i) fails, therefore we should
not try to "ifb_free_one()" on "i" since it failed
2) the loop iteration first increments "i", then it
check for error
Therefore we must decrement "i" twice before the first
free during the cleanup. One to "undo" the for() loop
increment, and one to "skip" the ifb_init_one() case which
failed.

Andrew and I both missed that thread, sorry.
I'm about to crash, can you or Linus handle the correction?
