hai all,
Is it possible to call call_usermodehelper from interrupt context.
I want to call a user program from the keyboard driver. When am calling,
it is hanging, and giving the error that
<0> Kernel panic : Aiee, killing interrupt handler
In interrupt handler -- not syncing.
I am using Redhat linux 9.
Can anybody please help me.
Thanks&Regards,
P.Manohar,

No. You'll need to run schedule_work() and then run call_usermodehelper()
from within the work function.

Of course not! I've seen this message before. Either it's a joke
or you have no clue about what interrupts are.
