 GIT_TEST_SPLIT_INDEX=<boolean> forces split-index mode on the whole
 test suite. Accept any boolean values that are accepted by git-config.
 
+GIT_TEST_PASSING_SANITIZE_LEAK=<boolean> when compiled with
+SANITIZE=leak will run only those tests that have whitelisted
+themselves as passing with no memory leaks. Tests can be whitelisted
+by setting "TEST_PASSES_SANITIZE_LEAK=true" before sourcing
+"test-lib.sh" itself at the top of the test script. This test mode is
+used by the "linux-leaks" CI target.

 GIT_TEST_PROTOCOL_VERSION=<n>, when set, makes 'protocol.version'
 default to n.
