Subject: [PATCH 1/2] 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.
