Flyspray misinterprets lore.kernel.org links as emails due to the @ if you replace it with %40 that seems to work.

This problem seems to be caused by the lack of support for Intel's new generation of Bluetooth in the 5.10 kernel, causing systemd-udevd to perform an operation repeatedly and take up a lot of CPU
This series of patches (a total of five) has improved the kernel's support for it, so this problem can be fixed, so the actual fix for this problem is [PATCH v8 5/5] Bluetooth: btusb: Map Typhoon peak controller to BTUSB_INTEL_NEWGEN, but it depends on the other four patches,
So it seems we should treat them as a whole patch set (just like Ubuntu does)
