Also let us merge it unti kernel side change is in reasonable shape.

From what I understand it may take several days or some other not-precisely specified time until "nightly" builds, which we use in the BPF CI, pick up the change. Hence, I was under the impression that we should attempt to merge it sooner rather than later once it's ready to be merged. The kernel changes are in good enough shape to show feasibility, so I don't really see why not, but it's your call.

yonghong-song abandoned D126223: [Clang][Sema] Fix a SemaType/VisitTagTypeLoc assertion.

Sorry. I missed this patch somehow and did another patch https://reviews.llvm.org/D126223. My patch skipped TL.setNameLoc(DS.getTypeSpecTypeNameLoc()); which probably not correct. Accept this patch and abandon my patch D126223.

The current 'summary' or commit message is too simple. Could you clarify some motivation why you need to add this instruction?
The change itself looks good to me. The kernel selftest test_verifier does test BPF_MOD instruction and I checked verifier code, BPF_MOD is handled similar to BPF_DIV which should be okay in most cases, so I didn't see a major issue here.

yonghong-song added a comment to D123800: [BPF] handle opaque-pointer for __builtin_preserve_enum_value.

The fix to prevent the crash looks good, but what should be the expected codegen for a global variable?
CO-RE needs a constant.
Are we assuming that the global data will be inited with some constant and a later pass will propagate it further into __builtin_preserve,
so at the end it will become a constant?

We probably should warn in both those cases; the variable clearly isn't "used" in any meaningful way.

@aaron.ballman @erichkeane Just updated the patch with a new implementation, which added a new BTFTagAttributedType instead of reusing existing AttributedType. It is quite complicated and various parts of clang are touched. I mostly just followed what AttributedType did but considering BTFTagAttributedType is C only so my current implementation may unnecessarily complicate things. I didn't have much test coverage either. It would be great you can give a look and let me know (1). what I am missing, (2). where I can simplify things, (3) a different approach if you see fit, (4). what additional tests I should have. Thanks!
