So, given the potential impact of this change, what testing have you done in terms of: - performance impact
I tested this on my machines and it gave a real performance improvement (11 to 8 seconds for a full kernel tree unlink, and cutting out latency for normal applications)
- sync() safety
that was exactly the synchronization point that's discussed here.
