How one is supposed to handle the reference count of a task_struct from a
kernel module?
get_task_struct() and put_task_struct() do not work, because the latter can't
be used from a module, since it calls __put_task_struct(), which is not
EXPORT_SYMBOL()'d.
I'm running 2.6.8.1.
Thanks in advance for your time,
Francesco Casadei

I don't think you are supposed to do anything that'd need to grab a
task_struct from modular code.
