That is very useful, thanks.
We (Boqun and others) are in the middle of Kangrejos now, so we may take a bit to reply, sorry.

Yeah, if this is the bad commit, I believe the issue has been fixed. Because that commit in linue-next indicated the problematic locking/core branck of tip was used:
eb57133305f6 rust: sync: Add basic atomic operation mapping framework 76eeb9b8de98 (tag: v6.17-rc5) Linux 6.17-rc5
one patch was missing in that version as I mentioned here [1]

Is this still an issue on next-20250916? As far as I can tell this has been fixed, but now there is another rust build issue, see https://lore.kernel.org/regressions/0fee48bb-7411-4414-b4e7-395a8c3d0f6c@heu... for more information.
