1# This file exports variables for each tunable used in the test suite. 2# 3# Different platforms use different names for most tunables. To avoid littering 4# the tests with conditional logic for deciding how to set each tunable, the 5# logic is instead consolidated to this one file. 6# 7# Any use of tunables in tests must use a name defined here. New entries 8# should be added to the table as needed. Please keep the table sorted 9# alphabetically for ease of maintenance. 10# 11# Platform-specific tunables should still use a NAME from this table for 12# consistency. Enter UNSUPPORTED in the column for platforms on which the 13# tunable is not implemented. 14 15UNAME=$(uname) 16 17# NAME FreeBSD tunable Linux tunable 18cat <<%%%% | 19ADMIN_SNAPSHOT UNSUPPORTED
