I did think about ctime issues when I applied the patch.

rename(2) is hardlink to new name followed by unlink of old name, so
internally link count changes twice (and the first "link to new" can
exceed max links and is even allowed to make the whole thing fail); but I
do not think of any other reason for this change in ctime.
