[Ocfs2-devel] [RFC] The reflink(2) system call v4.

[Sage Weil]

Hi Joel,

This version (with whatever flag simplifications are deemed appropriate) 
looks pretty good to me!

The only other thing I would like to see is a flag that makes copying the 
xattrs optional.  That's straying toward kitchen sink territory, but it 
seems like a natural enough interface once you're cherry-picking what to 
preserve in the reflink.  (Since you can always remove unwanted xattrs 
later, of course, it's certainly not a show-stopper.)

Thanks!
