Hello all,
I have one linked list data structure added to
a file in kernel source code which has some kernel
info. I want to acess that linked list structure from
user space. Is that possible??
Also how to add own system call usable at user
level from kernel module??

linux_lover.
Many people will tell you to use the /proc file-system.
I suggest you make a simple "character" driver and access
your kernel structure using ioctl() or mmap().
You don't add your own system call __ever__, even if you
are a long-time kernel developer. The current API already
has lots of standard interface capabilities. Thinking, even
for an instant, that you need more means that you don't
understand Unix/Linux.
