# DESCRIPTION:
# A zfs file system quota limits the amount of pool space
# available to a given ZFS file system dataset. Once exceeded, it
# is impossible to write any more files to the file system.
#
# STRATEGY:
# 1) Apply quota to the ZFS file system dataset
# 2) Exceed the quota
# 3) Attempt to write another file
# 4) Verify the attempt fails with error code 49 (EDQUOTA)
#
#

#
# cleanup to be used internally as otherwise quota assertions cannot be
# run independently or out of order
