From e5857d396f35e59e6fe96cf1178b0357cc3a1ea4 Mon Sep 17 00:00:00 2001 From: Daniel Latypov Date: Sat, 9 Jul 2022 11:19:58 +0800 Subject: kunit: flatten kunit_suite*** to kunit_suite** in .kunit_test_suites MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit We currently store kunit suites in the .kunit_test_suites ELF section as a `struct kunit_suite***` (modulo some `const`s). For every test file, we store a struct kunit_suite** NULL-terminated array. This adds quite a bit of complexity to the test filtering code in the executor. Instead, let's just make the .kunit_test_suites section contain a single giant array of struct kunit_suite pointers, which can then be directly manipulated. This array is not NULL-terminated, and so none of the test filtering code needs to NULL-terminate anything.
