Subject: [RFC] kobject and kset core changes and cleanups
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
