bottomhalf.c

[trulykyle]

Hi,

Thanks for the nice book.

But in the example bottomhalf.c, it is trying to sleep in the tasklet which will execute from interrupt context. Then the kernel will crash. I think work_queue or delayed_workqueue are the good candidate for sleep/block within the interrupt context.

thanks,
Kyle

Hi @trulykyle ,

You're right. We cannot sleep in the tasklet (atomic mode)[1] [2].
I will fix this recently.
Thanks for the feedback!
