Subject: [PATCH v2 5/5] bitfield: build kunit tests without structleak plugin
Date: Wed, 29 Sep 2021 14:27:13 -0700	[thread overview]
Message-ID: <20210929212713.1213476-6-brendanhiggins@google.com> (raw)
In-Reply-To: <20210929212713.1213476-1-brendanhiggins@google.com>

From: Arnd Bergmann <arnd@arndb.de>

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.
