[1/1] kbuild: Reject unexpected values for LLVM= https://git.kernel.org/kbuild/c/502678b88cb3b Please look out for regression or issue reports or other follow up comments, as they may result in the patch/series getting dropped or reverted. Patches applied to an "unstable" branch are accepted pending wider testing in -next and any post-commit review; they will generally be moved to the main branch in a week if no issues are found.
