Yeah but even if the file disappears, the open file descriptor is still
there, no? Does sysfs somehow make those disappear? I know debugfs does
(now, to some extent, it didn't always), but I thought sysfs was
refcounting things and didn't do that?

What did the userspace actually see? read() returned 0 so EOF?

(I guess I could test it, but it's getting late)

Your other questions are related - you need to consider the file in
sysfs and the open file descriptor separately.
