task_struct reference counting

task_struct reference counting

[Francesco Casadei]

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.
