From: Zhen Lei <thunder.leizhen@xxxxxxxxxx> Subject: lib: kunit: suppress a compilation warning of frame size lib/bitfield_kunit.c: In function `test_bitfields_constants': lib/bitfield_kunit.c:93:1: warning: the frame size of 7456 bytes is larger than 2048 bytes [-Wframe-larger-than=] } ^ As the description of BITFIELD_KUNIT in lib/Kconfig.debug, it "Only useful for kernel devs running the KUnit test harness, and not intended for inclusion into a production build". Therefore, it is not worth modifying variable 'test_bitfields_constants' to clear this warning. Just suppress it.
