That does not work when the message you are sending in-reply-to is no longer in the recipient's message box :)
Ah. Got it.
This is for linux-5.12.y tree.
Great, thanks.
And did you send the same patch twice?
No. Unfortunately, they're different due to swiotlb patches. I backported the patch to each kernel versions respectively.
What is the "other" patch for?
Another patch what I sent is for linux-5.10.y tree. Regarding linux-5.10.y's patch and linux-5.12.y's patch, below patch was applied only for linux-5.12.y tree and it made differences.
