This seems very similar to bug#2645

rsync 3.0.4 and 3.0.6 server-side do not seem to honor the -x option.

Reproducer:

# mkdir /testing
# mount -t tmpfs -o size=1M,nr_inodes=1000,mode=0700 tmpfs /testing
# touch /testing/{a,b,c,d,e}
# mkdir /testing/foo
# mount -t tmpfs -o size=1M,nr_inodes=1000,mode=0700 tmpfs /testing/foo
# touch /testing/foo/{a,b,c,d,e}
# mkdir /tmp/moo
# cd /tmp/moo
# touch a b c d e
# rsync -Havx --delete . /testing/
sending incremental file list
./
deleting foo/e
deleting foo/d
deleting foo/c
deleting foo/b
deleting foo/a
rsync: delete_file: rmdir(foo) failed: Device or resource busy (16)

Unless I'm missing something, -x should be honored by the server and should
refuse to cross the /testing/foo mountpoint to delete the files contained on
the 2nd RAMdisk.
