No, it won't, the code has changed in ways that won't make this happen
any more. The fix with the (!dir) part is on it's way, I could split
that out separately if you'd like, but then we'd have to fix up the
rejects because that patch looks different too even though the result
will be very similar.

Good question. The latter fix with (!dir) applies to .26 as well, but
the issue is hit so infrequently (only when adding the debugfs dir has
failed before) that I'm not sure it's worth it. And the master interface
issue isn't present before .27.
