Subject: [PATCH 0/3] refcounting improvements in sysfs.

This series tidies up the refcount of sysfs_dirents in sysfs,
using kref where appropriate and a new karef for s_active.
This achieves significant code simplification, especially the first
patch.

This is in part inspired by http://lwn.net/Articles/336224/ :-)
