[PATCH v2 5/5] bitfield: build kunit tests without structleak plugin

From: Brendan Higgins
Date: Wed Sep 29 2021 - 17:27:44 EST


From: Arnd Bergmann <arnd@xxxxxxxx>

The structleak plugin causes the stack frame size to grow immensely:

lib/bitfield_kunit.c: In function 'test_bitfields_constants':
lib/bitfield_kunit.c:93:1: error: the frame size of 7440 bytes is larger than 2048 bytes [-Werror=frame-larger-than=]

Turn it off in this file.
