Hello all,
this is my very first message in this list, and I'm very, very newbie on
linux kernel programming, I have a doubt, I need to modify a module to
pass a great size array (about 600KB) in user space to kernel use-it, I
think add more one IOCTL in his ioctl control of controled device
passing the pointer as argument but I don't want to copy this array
using copy_from_user() to kernel space because the size is too large,
there's some way to convert the user-space array address to kernel-space
address to use directly the original array ?
Thanks for all help
