This probably is a silly question, but....
Is is possible to open a file, mmap() it into memory, then pass the address of that map via an ioctl() call to the kernel, which will copy_from_user() that data?
Yeah, that's an odd concept, I know... I could always malloc() some memory, read the file in, and then ioctl() it. But, if I could get away with a direct mmap(), that would be much better for me.
