Note, there was activity in the linked ticket on bugzilla.kernel.org;
regzbot sadly is not able to detect this yet, this and other features to
improve interaction with b.k.o remain on the todo list for now (and
sadly likely will have to remain there for a few weeks, as I have some
other things I need to work on first for the project that made regzbot
possible)

I wonder why the fix for those two was not among the patches from akpm
