Hi XFS devs,

I'm a bit late to the party, but I'd like to respond to some comments at 
http://lwn.net/Articles/476263/#Comments
http://lwn.net/Articles/484709/

 > Could any of the fsync advocates post real code that does the atomic 
variant of open, write, close?

instead of blaming app devs for not doing the impossible.

I'd like to ask:
- Is there a tool to log all unsafe operations?
- What is the *right* way to update a file?

I've asked the last question multiple times, but nobody has been able to 
give me a proper answer.

Greetings,

Olaf
