Hotplug docs?

Hotplug docs?

[Erik Harrison]

I'm sure I'm just missing something, but I've perused the hotplug 
webpage, and googled till my eyes were sore, but I couldn't find it.

Is there a comprehensive list of the hotplug events generated by the 
kernel? Specifically by 2.6? A quick comparison of the .agent files on 
my machine tells me that the list on the sourceforge page is probably 
not comprehensive. Any pointers?

Not really :(

Everything that contains a kobject in sysfs will generate a hotplug
event in the 2.6 kernel.  That's a lot of different things these days.

If you do want to retify this lack of documentation, I would be glad to
add it to the hotplug web site or whereever.

thanks,

Given that the term "kobject" is a new one to me, I doubt I am equipped 
to. But I'll dive in. I'm nothing if not enthusiastic. A pointer to any 
info would be appreciated.

TO return to this old chestnut, I ran a grep -r through the 2.6.5 source 
tree for kobject_add and kobject_register, and found pitifully few 
entries - where else should I search to generate some docs?

Realize that all struct device objects contain a kobject.  The creation
and destruction of them cause the majority of hotplug events in the
kernel...  Also follow the hotplug_ops and see who uses them...

Good luck,

greg k-h
