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