31# DESCRIPTION:
32# Verify that extended attributes can use extra bonus space of a large
33# dnode without kicking in a spill block.
34#
35# STRATEGY:
36# 1. Create a file system with xattr=sa
37# 2. Set dnodesize to a legal literal value
38# 3. Create a file
39# 4  Store an xattr that fits within the dnode size
40# 4. Repeat 2-3 for all legal literal values of dnodesize values
41# 5. Unmount the file system
42# 6. Use zdb to check for missing SPILL_BLKPTR flag
43#
