Use WARN() in drivers/base/

2008-07-26T19:00:07+00:00

Use WARN() instead of a printk+WARN_ON() pair; this way the message
becomes part of the warning section for better reporting/collection.

driver core: Suppress sysfs warnings for device_rename().

driver core: Suppress sysfs warnings for device_rename().

Renaming network devices to an already existing name is not
something we want sysfs to print a scary warning for, since the
callers can deal with this correctly. So let's introduce
sysfs_create_link_nowarn() which gets rid of the common warning.

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: 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: rename "subsys" to "class_subsys" in internal class structure

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

make things easier when struct bus_type and struct class merge in the

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.

device create: convert device_create_drvdata to device_create

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

Now that device_create() has been audited, rename things back to the
original call to be sane.

Keep the device_create_drvdata macro around to make merges easier.
