Commit 52f7c21b was intended to move
/sys/o2cb to /sys/fs/o2cb, providing /sys/o2cb as a symlink for
backwards compatibility.  However, the merge apparently added the
symlink but failed to move the directory, resulting in a duplicate
filename error.  It's a one-line change that was missing.

/sys/fs is where we really want file system specific sysfs objects.

Ocfs2-tools has been updated to look in /sys/fs/o2cb. We can maintain
backwards compatibility with old ocfs2-tools by using a sysfs symlink. After
some time (2 years), the symlink can be safely removed. This patch also adds
documentation to make it easier for people to figure out what /sys/fs/o2cb
is used for.

The userspace ABI of ocfs2's internal cluster stack (o2cb) was broken by
commit c60b7178 "kset: convert ocfs2 to
use kset_create".  Specifically, the '/sys/o2cb' kset was moved to
'/sys/fs/o2cb'.  This breaks all ocfs2 tools and renders the
filesystem unmountable.

This fix moves '/sys/o2cb' back where it belongs.

Dynamically create the kset instead of declaring it statically.

Also use the new kobj_attribute which cleans up this file a _lot_.

We don't need a "default" ktype for a kset.  We should set this
explicitly every time for each kset.  This change is needed so that we
can make ksets dynamic, and cleans up one of the odd, undocumented
assumption that the kset/kobject/ktype model has.

This patch is based on a lot of help from Kay Sievers.

We need to work on cleaning up the relationship between kobjects, ksets and
ktypes.  The removal of 'struct subsystem' is the first step of this,
especially as it is not really needed at all.

Thanks to Kay for fixing the bugs in this patch.
