For the record, I can continue to upload clang snapshots for testing and
validating this plus the sooner this hits a tree that goes into -next,
the sooner the ClangBuiltLinux infrastructure can start testing it. I
assume there will not need to be many compiler side fixes but if
__counted_by has shown us anything, it is that getting this stuff
deployed and into the hands of people who want to use it is the only
real way to find corner cases to address. No strong objection from me if
you want to wait for clang-22 to actually be released though for more
access.

Cheers,
Nathan
