[PATCH 1/2] kernel: kcsan: kcsan_test: build without structleak plugin

From: Anders Roxell
Date: Mon Nov 28 2022 - 05:44:08 EST


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.
