Those errors aren't supposed to be something new or related with renaming... Before patch git hash 5354555 all messages passed to kd{Error,Warning} have gone nowhere but now they go to stderr by default. So, these is old errors, but previously masked.
Okay, thanks, that explains why I now see the messages when previously I did not. Commit 5354555 was pushed to git sufficiently close to the k->tde renaming patches. I would not have noticed because I was not updating my local source tree during the period I helped test the renaming patches with Slavek.
I opened bug report 1655 to address any of the new, previously unseen error and warning messages.
