Hi, Steven, IMHO, the problem is that the PCI_HOTPLUG_EVENT macro needs to include "linux/tracepoint.h" but it is not allowed in userspace. The entire change in v6 build fails with CONFIG_UAPI_HEADER_TEST=y: https://lore.kernel.org/lkml/202501190108.tRReJA1Z-lkp@xxxxxxxxx/T/#mae507b91b8b80c386dfa9e63fbbdd45826c2e003 (sorry, I did not see the problem because my local .config do not set CONFIG_UAPI_HEADER_TEST) Thanks Shuai
