Subject: [PATCH 0/3] refcounting improvements in sysfs.
Date: Wed, 24 Mar 2010 14:20:08 +1100 [thread overview]
Message-ID: <20100324031829.2136.66489.stgit@notabene.brown> (raw)
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/ :-)
