I understand your concern and appreciate the feedback. I've made some
adjustments to the patch by directly placing the code to adjust the commit
timestamp within the spinlock, aiming to keep it as efficient as possible. =
The
changes have resulted in just a few extra lines. Would this approach be
acceptable to you ?

Additionally, we're also doing performance tests for it and will share the
results once they're available.

Best Regards,
Hou zj
