# This file exports variables for each tunable used in the test suite.
#
# Different platforms use different names for most tunables. To avoid littering
# the tests with conditional logic for deciding how to set each tunable, the
# logic is instead consolidated to this one file.
#
# Any use of tunables in tests must use a name defined here. New entries
# should be added to the table as needed. Please keep the table sorted
# alphabetically for ease of maintenance.
#
# Platform-specific tunables should still use a NAME from this table for
# consistency. Enter UNSUPPORTED in the column for platforms on which the
# tunable is not implemented.
UNAME=$(uname)
# NAME FreeBSD tunable Linux tunable
