# __stc_assertion_start
#
# ID:  xattr_012_pos
#
# DESCRIPTION:
# xattr file sizes count towards normal disk usage
#
# STRATEGY:
#	1. Create a file, and check pool and filesystem usage
#       2. Create a 200mb xattr in that file
#	3. Check pool and filesystem usage, to ensure it reflects the size
#	   of the xattr
#
# TESTABILITY: explicit
#
# TEST_AUTOMATION_LEVEL: automated
#
# CODING_STATUS: COMPLETED (2006-12-15)
#
# __stc_assertion_end
