Kernel Module to send Message to User Space Application
I want write kernel module to send message to user space application(usa).
Earlier i have written using netlink sockets, In this case first User space application sends message by filling its pid to kernel module, using
this pid kernel module can reply.
I want write module which doesn't know pid of usa,but has to send message.
(Kernel module has initiate sending message).
Is there any other concept(other than netlink socket) to achieve above.
