Hmm... poll isn't hooked up for bin files and the behavior isn't well
defined either.  The open file's event counter is never synchronized
to the backing node's.  Before the first kernfs_notify(), it won't
trigger and after always.  We'll prolly need to define that better.
What's the use case that you're interested in?

Thanks.
