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@intel.com/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@intel.com/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@intel.com>
| Closes: https://lore.kernel.org/oe-kbuild-all/202308171545.aknH9sjQ-lkp@intel.com/
Note: the linux-next/master HEAD 47762f08697484cf0c2f2904b8c52375ed26c8cb builds fine.
It may have been fixed somewhere.

Looks like the commit added some lines before this union, and so the
line numbers have changed. AFAIK this is not a new issue:

Indeed, this was fixed by the upgrade to a newer bindgen in
`rust-next`, see commit 08ab786556ff ("rust: bindgen: upgrade to
0.65.1").
