Hmm. I sent this with "--in-reply-to" option of git send-email with your e-mail's message-id but it didn't work well. This is for linux-5.12.y tree. > > 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. Best Regards, Chanho Park
