  There was a bug in at least -rc5[1] that was considered already fixed in
  -rc4[2]. The later announcements didn't mention it anymore.

  It seems it was fixed for most users though. Trond?

Trond sent a fix to the nfs list on 27 Nov for "fileid changed" but I don't
know if this is the same bug you're seeing.  The patch was to
nfs_same_file() and I can send it if you want.  As far as I know the patch
made it upstream.
