Hello. Do anyone have an idea how to send a notifier to a user space application ? I can do char device or socket, and let the user poll it, but it feels like an overkill.. What about signals ? is it reliable ? I wish there was a user-space form of the notifiers mechanism...
Hi, I'm not sure if it would be useful, but the function "call_usermodehelper()" (defined in include/linux/kmod.h) can be used to execute a user space binary from the kernel space. It is used by the hot-plug mechanism to notify user space about the new devices added to the kernel.
