When the kernel is compiled with W=1 option, a warning is reported if a .c file exports a symbol but does not include export.h header file. This warning was added in below patch, which merged recently: commit a934a57a42f6 ("scripts/misc-check: check missing #include <linux/export.h> when W=1") Fix this issue in Hyper-V drivers. This does not bring any functional changes. The one in drivers/hv/vmbus_drv.c is going to be fixed with https://lore.kernel.org/all/20250611072704.83199-2-namjain@xxxxxxxxxxxxxxxxxxx/ so it is not included in this series.
