I sent a very minor v4 re-roll of this which should be ready for "next",
i.e. it addresses comments (including yours) on the v3:
https://lore.kernel.org/git/cover-v4-0.4-00000000000-20220227T102256Z-avarab@gmail.com/

If you're considering branch name/log message changes before merging (it
would be fine without) I'd suggest:

    ab/test-lib-leak-diagnostics
    
    Spend more CPU to emit meaningful stack traces when testing under
    SANITIZE=leak, and allow overriding ASAN and LSAN options from the
    environment without breaking our tests in cases where they relied on
    setting their own options.
