Userspace agent crash and kernel module

[Kevin Wilson]

Hi,
I want to write a kernel module which interacts with a userspace daemon.
There are cases when the userspace daemon can terminate by some signals.
There are also cases where the userspace daemon can crash (in some abnormal
cases). Is there a way that the kernel module will be aware of such
userspace agent crash, in order to reset its state ?

Regards,
Kevin
