The patch will show up in the next release of the linux-next tree (usually sometime within the next 24 hours during the week.) The patch will hopefully also be merged in Linus's tree for the next -rc kernel release. If you have any questions about this process, please let me know. >From e2459108b5a0604c4b472cae2b3cb8d3444c77fb Mon Sep 17 00:00:00 2001 From: "taehyun.cho" Date: Thu, 7 Jan 2021 00:46:25 +0900 Subject: usb: gadget: enable super speed plus Enable Super speed plus in configfs to support USB3.1 Gen2. This ensures that when a USB gadget is plugged in, it is enumerated as Gen 2 and connected at 10 Gbps if the host and cable are capable of it. Many in-tree gadget functions (fs, midi, acm, ncm, mass_storage, etc.) already have SuperSpeed Plus support.
