Yeah, that's what ocfs2 does.

Maybe it'll be easier because btrfs can just toss inodes (leafs with  
inodes, I suppose) whose checksums are invalid.  fsck.{ext*,ocfs2}  
gets to play the fun game of trying to figure out which of a set of  
conflicting fields is actually the one that isn't corrupt.  It's not  
great.

(rule of thumb: every time fsck has to ask an interactive question,  
instead of being able to tell from disk structures, there's a design  
failure.)

So maybe it doesn't matter.  Still, it seems sloppy.

Maybe I could roll a patch some day to demonstrate what I'm talking  
about instead of just whining in email.  That'd be something!
