Linking with kernel code (Makefile)
Thanks for your advice,
I already know one way to accomodate shared memory between a user process and the kernel.
This is done by making a character device which allocates memory in the kernel, then from the user appl, using the mmap function of the driver.
I was only wondering why I could not link my code with the kernel, though they are compiled together, this means I should be able to use any function in the kernel files as long as I succeed to define it right
So in my question X would be any application, Y would be linking my code with the kernel and Z would be to get more control over structures

Hi Kernel World,
I'm new to linux-kernel developement, so I would appreciate any help.What I want to do:
create a shared memory segment between user space and kernel spaceGenerally, you can get the most useful help from linux-kernel if as well as
saying what you do you also say _why_. So if you say you are developing an
application to do X, and you want to interact with the kernel in a certain
way Y because Z, then if Y is the correct way to accomplish X, people will
tell you how. If, however, there is a better way, they will tell you this
instead. Sorry, I don't know anything about the particular question youposted, but if you want my own uneducated guess, I will guess that it's not
possible.
