driver-core: make devt_attr and uevent_attr static

2007-07-11T23:09:06+00:00

devt_attr and uevent_attr are either allocated dynamically with or
embedded in device and class_device as they needed their owner field
set to the module implementing the driver.  Now that sysfs implements
immediate disconnect and owner field removed from struct attribute,
there is no reason to do this.  Remove these attributes from
[class_]device and use static attribute structures instead.

sysfs: kill unnecessary attribute->owner

2007-07-11T23:09:06+00:00

sysfs is now completely out of driver/module lifetime game.  After
deletion, a sysfs node doesn't access anything outside sysfs proper,
so there's no reason to hold onto the attribute owners.  Note that
often the wrong modules were accounted for as owners leading to
accessing removed modules.

This patch kills now unnecessary attribute->owner.  Note that with
this change, userland holding a sysfs node does not prevent the
backing module from being unloaded.

For more info regarding lifetime rule cleanup, please read the
following message.

(tweaked by Greg to not delete the field just yet, to make it easier to
merge things properly.)

Driver core: keep PHYSDEV for old struct class_device

2007-06-08T19:41:07+00:00

Class-devices created by "struct class_device" are going to be replaced
by "struct device". Keep the deprecated PHYSDEV* variables for the already
"deprecated" struct class_device" devices.

remove "struct subsystem" as it is no longer needed

2007-05-03T01:57:59+00:00

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.

driver core: fix namespace issue with devices assigned to classes

2007-04-27T17:57:28+00:00

  - uses a kset in "struct class" to keep track of all directories
    belonging to this class
  - merges with the /sys/devices/virtual logic.
  - removes the namespace-dir if the last member of that class
    leaves the directory.

There may be locking or refcounting fixes left, I stopped when it seemed
to work with network and sound modules. :)

Driver core: remove class_device_rename

2007-02-23T22:52:08+00:00

No one uses it, and it wasn't exported to modules, so remove it.  The
only other user of it was the network code, which is now converted to
use struct device instead.

driver core: delete virtual directory on class_unregister()

2006-12-13T23:38:45+00:00

Class virtual directory is created as the need arises.
But it is not deleted when the class is unregistered.
