Is it possible to use _syscallX macros in loadable device drivers. I first of all have had problems with "errno: wrong version or undefined".It seems to be defined in linux/lib/errno.c. I want to be able to use the system calls signal, getitimer and setitimer in my driver Does anybody know how I can get a _syscall() macro to work in my loadable device driver??
Any advice would be much appreciated.
