Ok, further progress: add $this->bbcode_second_pass_code('', '#include <linux/slab.h>') to xce_dev.c
Then, in the same xce_dev.c @ line 59 change variable .ioctl to .unlocked_ioctl as it looks like ioctl has been removed from new
kernel source. I don't know what this will affect, but now the module compiles.
