35# DESCRIPTION:
36#	The minimum volume size for swap should be a multiple of 2 pagesize
37#	bytes.
38#
39# STRATEGY:
40#	1. Get test system page size.
41#	2. Create different size volumes.
42#	3. Verify 'swap -a' has correct behaviour.
43#
44# TESTABILITY: explicit
45#
46# TEST_AUTOMATION_LEVEL: automated
47#
48# CODING_STATUS: COMPLETED (2006-12-12)
