This series consolidates the code to implement configfs attributes by providing the ->show and ->store method in common code and using container_of in the methods to access the containing structure. This reduces source and binary size of configfs consumers a lot. Changes since V1: - a couple fixes for unintended changes in the uvc driver - moved a few CONFIG_ATTR() statements around - fixed up the documentation and samples in the last patch - added a little rather pointless blurb to the patch description for various patches

[Ocfs2-devel] [PATCH 01/23] configfs: add show and store methods to struct configfs_attribute
Add methods to struct configfs_attribute to directly show and store
attributes without adding boilerplate code to every user. In addition
to the methods this also adds 3 helper macros to define read/write,
read-only and write-only attributes with a single line of code.

[Ocfs2-devel] [PATCH 03/23] usb-gadget/uvc: use per-attribute show and store methods
UVC is a little different from other configfs consumers in that it wants
different function and field names from the exposed attribute name, so
it keeps it's local macros to define attributes instead of using the common
ones.

[Ocfs2-devel] [PATCH 19/23] target: use per-attribute show and store methods
This also allows to remove the target-specific old configfs macros, and
gets rid of the target_core_fabric_configfs.h header which only had one
function declaration left that could be moved to a better place.

[Ocfs2-devel] [PATCH 21/23] ocfs2/cluster: move locking into attribute store methods
The test and separate set bit scheme was racy to start with, so move to do
a test_and_set_bit after doing the earlier error checks inside the actual
store methods. Also remove the locking for the local attribute which
already has a different scheme to synchronize.

[Ocfs2-devel] [PATCH 23/23] configfs: remove old API
Remove the old show_attribute and store_attribute methods and update
the documentation. Also replace the two C samples with a single new
one in the proper samples directory where people expect to find it.
