I'm seeing issues with the ftrace "Test file and directory owership
changes for eventfs" test on several platforms, including both 32 Arm
and whatever random x86_64 box Linaro have in their lab.  The logs
aren't terribly helpful since they just log a "not ok", example here:

  https://lava.sirena.org.uk/scheduler/job/265221#L3252

Bisects land on "eventfs: Do not differentiate the toplevel events
directory" as having introduced the issue.  Other stables don't seem to
be affected.

Bisect log (this one from a Raspberry Pi 3 in 32 bit mode):
