Hi Hiroki, I'm recently working on cleaning up malloc(M_WAITOK), and found that the sys/dev/usb stack is also used by bootloader. Currently stand/usb fails to compile ( since the commit 9e4e7bcaef3f 2022/8/23 ) and I have some WIP patches. I do not find a good page about its usage. How can I test stand/usb ? Or it has no usage any more and should be retired ?
Best regards, Zhenlei
