Hi Naresh, Thanks for the report. It looks like AKPM is already aware. https://lore.kernel.org/llvm/20221022163356.f5e08eeefe66fc71845be861@linux-foundation.org/
Naresh, for future reports, can you use our newer mailing list <llvm@lists.linux.dev> rather than our older one (<clang-built-linux@googlegroups.com>). I haven't actually closed the old one, but the new one is syndicated on lore. https://lore.kernel.org/llvm/
