I am not opposed to the removal of an unused function: I understand
the value in the removal, and I also understand the reasons to keep
it. I was just pointing the reason of why we got here: we merged patch
1/2 but ended up never merging patch 2/2 because we always spot some
additional work required and it's a very low priority bug. If this
function is removed, the next person to try to ressurrect the ddi
personality patch can quickly resurrect it or even write a new
implementation from scratch. It is your decision :)
