I have a question about the communication between Linux kernel, and
one daemon on that host. What is the better way to let kernel inform
a daemon something happened. I know signal should work, But somehow
I do not want to use it. I did not use unix socket before, But since
unix socket will use a file, It seems it can not be used in kernel.
The problem I ran into looks like this:
Kernel receive a message, this message is not aimed to one application,
but the kernel needs to handle it, and will pass
this message to a daemon after the kernel handling. And daemon
will also handle this message.
Thanks. Please also cc to me.
