The code shown above requires Clang 23 while this code has been built
with Clang 22. This build error should already have been fixed in
Linus' master branch since Linus has merged a pull request that bumps
the Clang version required for lock context analysis to 23:
Ingo Molnar, [GIT PULL] locking updates for v7.2, June 14
(https://lore.kernel.org/all/ai6O4a4UstIWIsFv@gmail.com/).
