From: Geert Uytterhoeven <geert@xxxxxxxxxxxxxx> Subject: math: make RATIONAL tristate Patch series "math: RATIONAL and RATIONAL_KUNIT_TEST improvements". This series makes the RATIONAL symbol tristate, so it is not forced builtin if all users are modular, and makes the RATIONAL_KUNIT_TEST depend on RATIONAL, to avoid enabling RATIONAL if there are no real users. This patch (of 2): All but one symbols that select RATIONAL are tristate, but RATIONAL itself is bool. Change it to tristate, so the rational fractions support code can be modular if no builtin code relies on it.
