class: change internal semaphore to a mutex

2008-07-22T04:54:52+00:00

Now that the lockdep infrastructure in the class core is in place, we
should be able to properly change the internal class semaphore to be a
mutex.

David wrote the original patch, and Greg fixed it up to apply properly
due to all of the recent changes in this area.

class: add lockdep infrastructure

2008-07-22T04:54:52+00:00

This adds the infrastructure to properly handle lockdep issues when the
internal class semaphore is changed to a mutex.

Matthew wrote the original patch, and Greg fixed it up to work properly
with the class_create() function.

class: rename "sem" to "class_sem" in internal class structure

2008-07-22T04:54:52+00:00

This renames the struct class "sem" field to be "class_sem" to make
things easier when struct bus_type and struct class merge in the future.
It also makes grepping for fields easier as well.

Based on an idea from Kay.

This renames the struct class "interfaces" field to be
"class_interfaces" to make things easier when struct bus_type and struct
class merge in the future.  It also makes grepping for fields easier as
well.

class: move driver core specific parts to a private structure

2008-07-22T04:54:51+00:00

This moves the portions of struct class that are dynamic (kobject and
lock and lists) out of the main structure and into a dynamic, private,
structure.

Driver Core: add ability for class_find_device to start in middle of list

2008-07-22T04:54:47+00:00

This mirrors the functionality that driver_find_device has as well.

We add a start variable, and all callers of the function are fixed up at
the same time.

The block layer will be using this new functionality in a follow-on
patch.
