[PATCH AUTOSEL 5.10 31/47] drivers/base: build kunit tests without structleak plugin

From: Sasha Levin <sashal@kernel.org>
Date: 2021-03-02 13:34:20
Also in: lkml
Subsystem: driver core, kobjects, debugfs and sysfs, the rest · Maintainers: Greg Kroah-Hartman, "Rafael J. Wysocki", Danilo Krummrich, Linus Torvalds

From: Arnd Bergmann <arnd@arndb.de>

[ Upstream commit 38009c766725a9877ea8866fc813a5460011817f ]

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.
