Listing file clones

Use the mmclone command to display status for specified files.

The show keyword of the mmclone command provides a report to determine the current status of one or more files. When a file is a clone, the report will show the parent inode number. When a file was cloned from a file in a snapshot, mmclone show displays the snapshot and fileset information.

Consider the following scenario:

The ls command is issued to show all img files in the current directory:
```
ls -ils *.img
```
The system displays output similar to the following:
```
148485 5752576 -rw-r--r-- 1 root root 21474836480 Jan  9 16:19 test01.img
```

A file clone is then created with the following commands:

mmclone snap test01.img base.img
mmclone copy base.img test02.img

After the file clone is created, the mmclone show command is issued to show information about all img files in the current directory:

mmclone show *.img

The system displays output similar to the following:

Parent  Depth   Parent inode   File name
------  -----  --------------  ---------
   yes      0                  base.img
    no      1          148488  test01.img
    no      1          148488  test02.img

A subsequent ls command would display output similar to the following:

 ls -ils *.img
148488 5752576 -rw-r--r-- 3 root root 21474836480 Jan  9 16:25 base.img
148485       0 -rw-r--r-- 1 root root 21474836480 Jan  9 16:19 test01.img
148480       0 -rw-r--r-- 1 root root 21474836480 Jan  9 16:25 test02.img
