# DESCRIPTION:
|
|
# Ensure stats presented in /proc/spl/kstat/zfs/dbufstats are correct
|
|
# based on /proc/spl/kstat/zfs/dbufs.
|
|
#
|
|
# STRATEGY:
|
|
# 1. Generate a file with random data in it
|
|
# 2. Store output from dbufs kstat
|
|
# 3. Store output from dbufstats kstat
|
|
# 4. Compare stats presented in dbufstats with stat generated using
|
|
# dbufstat and the dbufs kstat output
|
|
#
|
