# DESCRIPTION:
#	'zpool history' can copes with many simultaneous command.
#
# STRATEGY:
#	1. Create test pool and test fs.
#	2. Loop 100 times, set properties to test fs simultaneously.
#	3. Wait for all the command execution complete.
#	4. Make sure all the commands was logged by 'zpool history'.
#
# TESTABILITY: explicit
#
# TEST_AUTOMATION_LEVEL: automated
