Make error: implicit declaration of funtion

Hey there, trying to compile on galliumOS kernel 4.8.17 and getting the following make error - sorry I'm a bit of a C noob so not sure where to start. Suggestions?

make -C /lib/modules/4.8.17-galliumos/build M=/media/sd/Downloads/exfat-nofuse modules make[1]: Entering directory '/usr/src/linux-headers-4.8.17-galliumos' CC [M] /media/sd/Downloads/exfat-nofuse/exfat_core.o CC [M] /media/sd/Downloads/exfat-nofuse/exfat_super.o /media/sd/Downloads/exfat-nofuse/exfat_super.c: In function ‘exfat_create’: /media/sd/Downloads/exfat-nofuse/exfat_super.c:751:47: error: implicit declaration of function ‘current_time’ [-Werror=implicit-function-declaration] dir->i_ctime = dir->i_mtime = dir->i_atime = current_time(dir);
