Re: [PATCH] More Driver Core patches for 2.6.10-rc1

[PATCH] small sysfs cleanups

The patch below does the following cleanups for the sysfs code:
- remove the unused global function sysfs_mknod
- make some structs and functions static

Please check whether this patch is correct, or whether some of the
things I made static should be used globally in the forseeable future.
