Hi Marco, First bad commit (maybe != root cause): tree: https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git master head: 47762f08697484cf0c2f2904b8c52375ed26c8cb commit: 7a0fd5e1678505534573b3c14c6ff69ed8592596 [9940/10848] compiler_types: Introduce the Clang __preserve_most function attribute config: x86_64-rhel-8.3-rust (https://download.01.org/0day-ci/archive/20230817/202308171545.aknH9sjQ-lkp@xxxxxxxxx/config) compiler: clang version 16.0.4 (https://github.com/llvm/llvm-project.git ae42196bc493ffe877a7e3dff8be32035dea4d07) reproduce: (https://download.01.org/0day-ci/archive/20230817/202308171545.aknH9sjQ-lkp@xxxxxxxxx/reproduce) If you fix the issue in a separate patch/commit (i.e. not just a new version of the same patch/commit), kindly add following tags | Reported-by: kernel test robot <lkp@xxxxxxxxx> | Closes: https://lore.kernel.org/oe-kbuild-all/202308171545.aknH9sjQ-lkp@xxxxxxxxx/ Note: the linux-next/master HEAD 47762f08697484cf0c2f2904b8c52375ed26c8cb builds fine. It may have been fixed somewhere.
