Subject: [RFC 2/3] drivers/base: build kunit tests without structleak plugin
Date: Mon, 25 Jan 2021 13:45:27 +0100 [thread overview]
Message-ID: <20210125124533.101339-3-arnd@kernel.org> (raw)
In-Reply-To: <20210125124533.101339-1-arnd@kernel.org>
From: Arnd Bergmann <arnd@arndb.de>
The structleak plugin causes the stack frame size to grow immensely:
drivers/base/test/property-entry-test.c: In function 'pe_test_reference':
drivers/base/test/property-entry-test.c:481:1: error: the frame size of 2640 bytes is larger than 2048 bytes [-Werror=frame-larger-than=]
481 | }
| ^
drivers/base/test/property-entry-test.c: In function 'pe_test_uints':
drivers/base/test/property-entry-test.c:99:1: error: the frame size of 2592 bytes is larger than 2048 bytes [-Werror=frame-larger-than=]
Turn it off in this file.
