rsync of a reflink from OCFS2

[Kevin Korb]

It would still be downloading the whole file only to write out a new
one.  Rsync writes out a whole new file because it assumes it is doing
so locally.  The source of that new file can be a combination of parts
of the existing file and parts of the remote file but it still writes
the whole thing.  --inplace helps with that somewhat but you will
probably still write all of the file after the first difference.
