Subject: [PATCH 1/2] kernel: kcsan: kcsan_test: build without structleak plugin
Building kcsan_test with strucleak plugin enabled makes the stack frame
size to grow.
kernel/kcsan/kcsan_test.c:704:1: error: the frame size of 3296 bytes is larger than 2048 bytes [-Werror=frame-larger-than=]
Turn off the structleak plugin checks for kcsan_test.
Suggested-by: Arnd Bergmann <arnd@...db.de>
