- When replacing a non-dir with a symlink/hard-link/device/special-file,
the update should now be done in an atomic manner.
- - Fixed a free of the wrong pointer in uncache_tmp_xattrs() (which only
- sometimes affects an --xattr transfer when --backup is used).
+ - Avoid re-sending xattr info for hard-linked files w/the same xattrs
+ (protocol 31).
- When backing up a file, try to hard-link the file into place so that the
upcoming replacement of the destination file will be atomic.
