commit: caffe5f36f39ef62d58383b77dfdce931104f8c2 [/575] bcachefs: Compatibility with v6.18
config: x86_64-buildonly-randconfig-001-20251016 (https://download.01.org/0day-ci/archive/20251016/202510160526.gaQGq4Nb-lkp@intel.com/config)
compiler: clang version 20.1.8 (https://github.com/llvm/llvm-project 87f0227cb60147a26a1eeb4fb06e3b505e9c7261)
reproduce (this is a W=1 build): (https://download.01.org/0day-ci/archive/20251016/202510160526.gaQGq4Nb-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/202510160526.gaQGq4Nb-lkp@intel.com/
Note: the bcachefs/master HEAD bb35ade3e8bb7af67734b746f416598002822df8 builds fine.
It only hurts bisectability.
