new to kernel programming, heres a tip on global structs

[Dwayne RIght]

global, both dynamic and static data structures in the linux kernel
can be used for simple messaging

you can use global data structures in linked list and binary tree format

also with a global struct system, which is intended for messaging, can
be used for modules such as code in the kernel, like a loop reading
the global struct hitting a global struct member flag defined in an
enumerator in a function in a module and stopping the loop in the
kernel or elsewhere, or moving to another function

or it can be used to send string messages between functions

im new to kernel programming, when i get time i'll do stuff like read
the docs and try to put sqlite3 in the kernel and try to write gui
programs for kernel development, like a gui makefile program, but
hackers do use linux
