ok so you are looking for below code:
some_func()
{
set_register_value
x_varia
By driver code , I mean the code which set the register values and
wait till the values is set (via an interrupt handler) before
continues doing something else

Sorry, I mean
I want to set a bit in a HW Register 1. HW will send an interrupt
when setting the register is done.
I want my driver code to block until the interrupt is sent from the HW.

In my driver code,
I want to set a bit in a HW Register 1. HW will send an interrupt
when setting the register is done.
I don't want my driver code to block until the interrupt is sent from the HW.

Hi,
I read this article http://www.linuxjournal.com/article/5833 to learn
about spinlock. I try this to use it in my kernel driver.
Here is what my driver code needs to do:
In f1(), it will get the spin lock, and caller can call f2() will wait
for the lock since the spin lock is not being unlock.
