make headers_install for out-of-tree modules

[danielhilst@gmail.com (Daniel.)]

Hi,

thanks for the replies

Well, I'm using out-of-tree for development, I use it in one tree
while working and on another at home, so I keep my module out-of-tree
at only one repository, and compile against too trees. This is my
header[1], it doesn't have anything special, only ioctl definitions. I
read that this header processing is mainly because of libc and
syscalls integration. Since I don't mess with syscalls and libc stuff
do I need to process them too? When and why this header processing
applies?
