# DESCRIPTION:
# read/write/create/delete xattr on a clone filesystem
#
#
# STRATEGY:
#	1. Create an xattr on a filesystem
#	2. Snapshot the filesystem and clone it
#       3. Verify the xattr can still be read, written, deleted
#	4. Verify we can create new xattrs on new files created on the clone
#
