[PATCH 5.14 131/169] bitfield: build kunit tests without structleak plugin

From: Greg Kroah-Hartman
Date: Mon Oct 25 2021 - 15:57:19 EST


From: Arnd Bergmann <arnd@xxxxxxxx>

[ Upstream commit a8cf90332ae3e2b53813a146a99261b6a5e16a73 ]

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.
