[PATCH] Driver core: Use klist_del() instead of klist_remove().

2005-06-30T05:48:05+00:00

Use klist_del() instead of klist_remove() when unregistering devices.
This will prevent a deadlock when executing a recursive unregister using
device_for_each_child().

[PATCH] Driver core: change device_attribute callbacks

2005-06-20T22:15:31+00:00

This patch adds the device_attribute paramerter to the
device_attribute store and show sysfs callback functions, and passes a
reference to the attribute when the callbacks are called.

[PATCH] Use a klist for device child lists.

2005-06-20T22:15:23+00:00

- Use klist iterator in device_for_each_child(), making it safe to use for
  removing devices.
- Remove unused list_to_dev() function.
- Kills all usage of devices_subsys.rwsem.

[PATCH] Add a klist to struct device_driver for the devices bound to it.

2005-06-20T22:15:16+00:00

- Use it in driver_for_each_device() instead of the regular list_head and stop using
  the bus's rwsem for protection.
- Use driver_for_each_device() in driver_detach() so we don't deadlock on the
  bus's rwsem.
- Remove ->devices.
- Move klist access and sysfs link access out from under device's semaphore, since
  they're synchronized through other means.

[PATCH] Add a semaphore to struct device to synchronize calls to its driver.

2005-06-20T22:15:12+00:00

This adds a per-device semaphore that is taken before every call from the core to a
driver method. This prevents e.g. simultaneous calls to the ->suspend() or ->resume()
and ->probe() or ->release(), potentially saving a whole lot of headaches.

It also moves us a step closer to removing the bus rwsem, since it protects the fields
in struct device that are modified by the core.

[PATCH] sysfs: (driver/base) if show/store is missing return -EIO

2005-06-20T22:15:02+00:00

sysfs: fix drivers/base so if an attribute doesn't implement
       show or store method read/write will return -EIO
       instead of 0.
