From d8310914848223de7ec04d55bd15f013f0dad803 Mon Sep 17 00:00:00 2001 From: Tiezhu Yang Date: Mon, 5 Feb 2024 14:09:21 +0800 Subject: [PATCH] kasan: docs: update descriptions about test file and module After commit f7e01ab828fd ("kasan: move tests to mm/kasan/"), the test file is renamed to mm/kasan/kasan_test.c and the test module is renamed to kasan_test.ko, so update the descriptions in the document. While at it, update the line number and testcase number when the tests kmalloc_large_oob_right and kmalloc_double_kzfree failed to sync with the current code in mm/kasan/kasan_test.c.
