Ending up with the same code in core kernel in two different places is always 
a bad plan.  Oh man.  Just look at these two bodies of code, configfs is 
mostly just large tracts that are identical to sysfs except for name changes.  
Listen to what the code is trying to tell you!

SysFS:

struct kobject {
	const char		* k_name;
	char			name[KOBJ_NAME_LEN];
	struct kref		kref;
	struct list_head	entry;
	struct kobject		* parent;
	struct kset		* kset;
	struct kobj_type	* ktype;
	struct dentry		* dentry;
};

ConfigFS:

struct config_item {
	char			*ci_name;
	char			ci_namebuf[CONFIGFS_ITEM_NAME_LEN];
	struct kref		ci_kref;
	struct list_head	ci_entry;
	struct config_item	*ci_parent;
	struct config_group	*ci_group;
	struct config_item_type	*ci_type;
	struct dentry		*ci_dentry;
};

Big difference, huh?

As designer of configfs, could you please offer your take on why it cannot be 
rolled back into sysfs, considering that it is mostly identical already?
