2.6..15-rc7: CONFIG_HOTPLUG help text

[Grant Coady]

Hi there,

"
CONFIG_HOTPLUG:

This option is provided for the case where no in-kernel-tree
modules require HOTPLUG functionality, but a module built
outside the kernel tree does. Such modules require Y here.
"

This gives no indication it is required for udev.  Or is it me confused?

Thanks,
Grant.

It doesn't mention udev specifically, but it does say quite clearly
that it's for out-of-kernel stuff that requires hotplug, and udev is
such a thing.

udev is an out-of-tree kernel module?  Okay, why not bring it into 
the mainline kernel then?  ;)

Heh, ok, you are right, I guess my eyes skipped the "module" bit. I
guess it should say something along the lines of

 This option is provided for the case where no in-kernel-tree
 modules require HOTPLUG functionality, but a module (or
 other piece of software, like udev) built outside the kernel
 tree does.
 Such modules and other out-of-tree software require Y here.
 If in doubt say Y.

How's that for a better wording?

I'm not sure if the usage has drifted to udev now, or is valid 
for both udev and also out-of-tree stuff which seems to be now 
discouraged.

I wonder what else should be set for proper udev operation, and 
should it be the default for those arch support it?  IOW is there 
a place for CONFIG_UDEV (or whatever) as user-visible choice to 
switch the feature on/off?
