I was doing some testing on x86, which leads me to ask --- what's the
current thinking about post y2038 on 32-bit platforms such as x86? I

haven't made the transition in the VFS interfaces yet, despite a
comment in an LWN article from 2014 stating that "the first steps have
been taken; hopefully the rest will follow before too long".
