The inotify code was removed from golang.org/x/exp several years ago. Therefore importing it from that path prevents downstream consumers from using any module that makes use of more recent features of golang.org/x/exp. This change is a followup to google/cadvisor#2060 which was merged with #70889 This fixes #68478
