35# DESCRIPTION:
36# Write a file to the allowable ZFS fs size.
37#
38# STRATEGY:
39# 1. largest_file will write to a file and increase its size
40# to the maximum allowable.
41# 2. The last byte of the file should be accessbile without error.
42# 3. Writing beyond the maximum file size generates an 'errno' of
43# EFBIG.
