Commit e4a519635f75bde38aeb5b09f2ff4efbf73453e9:
Tidy up compile warnings by cleaning up types.
removed call to SLLocate which gutted the function of all functionality.
This patch restores the original behavior, with an additional fix
that zeros the update array in case SLLocate bails early.
v2: zero the update array instead of checking the return value.
SLLocate returns NULL both on failure and if the element is greater
than everything in the list
v3: Improve commit message

sorry for spamming, just realized it might be a good idea co CC the original
author and committer.
This was broken since 2.4.18 (2010). I guess it's safe to say that nobody
uses it. What are the policies on removing parts of API?
