These comments seem to mostly cover the same memcpy_nontemporal(), MOVNTI alignment, helper-level drain, and sanitizer/tracepoint tradeoff topics that were discussed for v7. The v8 changes keep the x86 non-temporal copy path unchanged, except for making the generic memcpy_nontemporal() fallback a void function-like macro. The remaining updates are clarifications in the cover letter and commit messages. So I do not plan further code changes for these comments at this point, unless someone points out a problem in the previous discussion. For the previous discussion, please see: https://lore.kernel.org/all/[email protected]/ Thanks, Zhe
