[PATCH v6 10/39] kmsan: Export panic_on_kmsan

From: Ilya Leoshkevich <iii@linux.ibm.com>
Date: 2024-06-21 00:26:59
Also in: linux-mm, linux-s390, lkml
Subsystem: kmsan, memory management, the rest · Maintainers: Alexander Potapenko, Andrew Morton, Linus Torvalds

When building the kmsan test as a module, modpost fails with the
following error message:

    ERROR: modpost: "panic_on_kmsan" [mm/kmsan/kmsan_test.ko] undefined!

Export panic_on_kmsan in order to improve the KMSAN usability for
modules.
