If you check patchwork using the Message-id of the individual patches (not the
cover letter) you'll see the status is Under Review which means it is under
active review. For example:

https://patchwork.kernel.org/project/linux-wireless/patch/20260916060325.854-2-kang.yang@oss.qualcomm.com/

Patches transition to that state when they are placed in my pending branch.

For best results when using patchwork you'll need to create an account and log
