    __ init function doesn't get called

    Hi all,

    I have a function with __init, but it is never called after booting-up. Anybody knows why?

    How does linux manage the sequence of __init functions, since there are many functions with __init ?

    also, where in the bootup process those __init functions are caled?

    __init doesn't mean that functions will be invoked "automatically"....people usually use macros something like core_initcall, arch_initcall,...etc with __init functions, and they have some execution sequence at bootup time. Those macros could be found at include/linux/init.h. And I think you could google on the internet to find out how __init functions are called in bootup process.
