34# DESCRIPTION:
35# read/write/create/delete xattr on a clone filesystem
36#
37#
38# STRATEGY:
39#	1. Create an xattr on a filesystem
40#	2. Snapshot the filesystem and clone it
41#       3. Verify the xattr can still be read, written, deleted
42#	4. Verify we can create new xattrs on new files created on the clone
43#
