Ioctl

Hello,

I'm very new at working with the kernel and device drivers and I'm trying to bring ours drivers up from a 2.6.16 kernel to 2.6.37. I'm noticing that ioctl() doesn't seem to be raound anymore, or at least I can't find it.

There is tons of stuff in my code that I don't yet understand which requires the ioctl function. What is the best way for me to either get the ioctl working in 2.6.37, or the quickest way to work around it???

Thanks,

ioctl() is still around.

fs/ioctl.c:
SYSCALL_DEFINE3(ioctl, unsigned int, fd, unsigned int, cmd, unsigned long, arg) {

What you almost certainly want is unlocked_ioctl(), which handles ioctl() calls but lacks the protection of the (soon to be removed) big kernel lock. If your driver is properly written, you should have no problem using unlocked_ioctl(), but do note that the function prototype is a little different.
