34# DESCRIPTION:
35# With 'compression' set, a file with non-power-of-2 blocksize storage space
36# can be freed as will normally.
37#
38# STRATEGY:
39#	1. Set 'compression' or 'compress' to on or lzjb
40#	2. Set different recordsize with ZFS filesystem
41#	3. Repeatedly using 'randfree_file' to create a file and then free its
42#	   storage space with different range, the system should work normally.
43#
44# TESTABILITY: explicit
45#
46# TEST_AUTOMATION_LEVEL: automated
47#
48# CODING_STATUS: COMPLETED (2006-07-26)
