Thank you for the reminder. A patch addressing the root cause of this
issue has already been submitted, but I am unsure if the solution is
fully appropriate and would appreciate further guidance. The relevant
patch series can be found here:
https://lore.kernel.org/all/20260314123741.1439792-1-gality369@gmail.com/.
Please take a look at the series.
Since you are not directly responsible for this, I didn't CC you on
the email to avoid causing any disruption. Apologies for any
inconvenience this may have caused.
Looking forward to your feedback,
ZhengYuan Huang
