30# DESCRIPTION:
31# Exercise the traversal suspend/resume code in async_destroy by
32# destroying a file system that has more blocks than we can free
33# in a single txg.
34#
35# STRATEGY:
36# 1. Create a file system
37# 2. Set recordsize to 512 to create the maximum number of blocks
38# 3. Set compression to off to force zero-ed blocks to be written
39# 4. dd a lot of data from /dev/zero to the file system
40# 5. Destroy the file system
41# 6. Wait for the freeing property to go to 0
42# 7. Use zdb to check for leaked blocks
43#
