Agreed. From what I have seen it's also the only file system code we have
that runs from interrupt handlers.

Also agreed. I haven't run NetBSD's softdep for a long time. From that I
have seen it doesn't deal well with system crashes or power outages.. If we
get a journalled FFS that works, I would be more than happy to see softdep
go.
