Using Sysfs uevents.

[Pranay Kumar Srivastava]

Hi,

I was playing with sysfs and I'm able to create kset and kobjects within them as well. I need to know how do I use the uevents of these kobjects that I create. For example while reading the code I found that certain events like ADD, DEL a couple more were there are apparently fired. Now currently I'm not handling these events, the ops field is null, so they don't bother me hence they are not mandatory?

If I were to actually do something with these events what it should be? Since my module runs fine and the uevents are supposed to be for userland applications (Hotplug) but the point is again how will a userspace application get to know about it? Does the application needs to create netlink sockets for it? If it does then why bother with the uevents of kobject?
