# DESCRIPTION:
#	Check the project used object accounting in zfs projectspace
#
#
# STRATEGY:
#	1. create a bunch of files by specific project
#	2. use zfs projectspace to check the used objects
#	3. change the project ID of test files and verify object count
#	4. delete files and verify object count
#
