[Just a quick info-relay reply here; I'm not a dev and don't use nfs.  
Hopefully someone with more information will reply given a few more hours 
or a day or two...]

The issue has been reported by several people, now, yes.  There has also 
been kernel dev discussion of a problem with nfs 2.x, with a patch in 
progress (don't know if it's applied yet), but it hasn't been clear, at 
least to me, whether all reports correspond to that or not.

Now that you know that much, if you don't get a better reply in a day or 
two, or while you are waiting, you can check the (btrfs) list archive for 
more information.
