24# DESCRIPTION:
25#	refquota, like regular quota, is loosely enforced.  A dataset
26#	can exceed its refquota by one transaction.  This loose enforcement
27#	used to cause problems upon receiving a datastream where its
28#	refquota is slightly exceeded.  This test confirms that we can
29#	successfully receive a slightly over refquota stream.
30#
31# STRATEGY:
32#	1. Create a filesystem.
33#	2. Set a refquota.
34#	3. Snapshot the filesystem.
35#	4. Send a replication stream to a new filesystem.
36#	5. On the original filesystem, fill it up to its quota.
37#	6. Snapshot the original filesystem again.
38#	7. Send an incremental stream to the same new filesystem.
