thanks for making this change and sticking with it!

Oh, and with this change, does your modprobe/rmmod crazy test now work?

It does but I wrote a test_syfs driver and I believe I see an issue with
this. I'll debug a bit more and see what it was, and I'll then also use
the driver to demo the issue more clearly, and then verification can be
an easy selftest test.
