driver model: anti-oopsing medicine

2008-08-21T17:15:36+00:00

Anti-oops medicine for the class iterators ... the oops was
observed when a class was implicitly referenced before it
was initialized.

[Modified by Greg to spit a warning back so someone knows to fix their code]

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.

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.
