[PATCH v2 3/3] kasan: delete CONFIG_KASAN_MODULE_TEST

From: Sabyrzhan Tasbolatov
Date: Sun Oct 13 2024 - 09:02:46 EST


Since we've migrated all tests to the KUnit framework,
we can delete CONFIG_KASAN_MODULE_TEST and mentioning of it in the
documentation as well.

I've used the online translator to modify the non-English documentation.

There are KASAN tests that allow verifying that KASAN works and can detect
-certain types of memory corruptions. The tests consist of two parts:

``CONFIG_KASAN_KUNIT_TEST``. These tests can be run and partially verified
automatically in a few different ways; see the instructions below.

-kernel log for KASAN reports.
-
Each KUnit-compatible KASAN test prints one of multiple KASAN reports if an
error is detected. Then the test prints its number and status.
