[RFC] kobject and kset core changes and cleanups

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 

So, I go on vacation for a week or so and come back to an overflowing
inbox.  Instead of trying to wade through all of that, I decide to
finish up the work Kay and I had started on cleaning up the kset core
code.

Here's a large patch series that is in my tree and should be for 2.6.25.
It does quite a few things:
	- lots of struct kset work and cleanup.  It's much simpler now
	  and will be documented while I still remember what is going
	  one...
	- almost all (only 5 left) struct kset are dynamically created
	  with the new function call, kset_create_and_register().  This
	  fixes up a lot of issues with static kobjects in structures
	  and other messy things like that.
	- struct bus_type is now split into two, a static and a dynamic
	  part.  The dynamic part is under control of the driver core,
	  and handles the ksets.  The static part is under control of
	  the bus that defined it.
	- decl_subsys() is now gone and buried, good riddance
	- subsys_attribute is now gone and replaced with:
	- kobj_attribute is now availble to make attributes for kobjects
	  MUCH simpler than ever before.  I've cleaned up some portions
	  of the kernel, and all older users of subsys_attribute have
	  been fixed.  This takes away one of the biggest complaints
	  about dealing with "raw" kobjects.
	- firmware subsystem has been all but removed as it was
	  pointless.


I'm posting the patches here so that people can take a look at them and
not be surprised when they go in to 2.6.25 in a few months and show up
in the next -mm releases.

One note, the efivars sysfs file removal patch is incorrect, and I'll be
fixing that up properly, so Matt, don't worry, I haven't forgotten :)

And hey, with all this work, we ended up removing more code than we
added, always a very good thing.

Now, on to face that scary inbox...

thanks,

greg k-h
