If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit a530412c823f22ad457115e74b2fac2df417341f Author: Brendan Higgins <brendanhiggins@xxxxxxxxxx> Date: Wed Sep 29 14:27:12 2021 -0700 thunderbolt: build kunit tests without structleak plugin [ Upstream commit 33d4951e021bb67ebd6bdb01f3d437c0f45b3c0c ] The structleak plugin causes the stack frame size to grow immensely when used with KUnit: drivers/thunderbolt/test.c:1529:1: error: the frame size of 1176 bytes is larger than 1024 bytes [-Werror=frame-larger-than=] Turn it off in this file. Linus already split up tests in this file, so this change *should* be redundant now.
