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

2005-06-30T05:48:05Z

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(). Signed-off-by Patrick Mochel Signed-off-by: Greg Kroah-Hartman

[PATCH] Driver core: change device_attribute callbacks

2005-06-20T22:15:31Z

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. Signed-off-by: Yani Ioannou Signed-off-by: Greg Kroah-Hartman

[PATCH] Use a klist for device child lists.

2005-06-20T22:15:23Z

- 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. Signed-off-by: Patrick Mochel Signed-off-by: Greg Kroah-Hartman

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

2005-06-20T22:15:16Z

- 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.

2005-06-20T22:15:12Z

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. Signed-off-by: Patrick Mochel Signed-off-by: Greg Kroah-Hartman

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

2005-06-20T22:15:02Z

sysfs: fix drivers/base so if an attribute doesn't implement show or store method read/write will return -EIO instead of 0. Signed-off-by: Dmitry Torokhov Signed-off-by: Greg Kroah-Hartman

[PATCH] kset_hotplug_ops->name shoudl return const char *

2005-06-20T22:15:01Z

kobject: change name() method in kset_hotplug_ops return const char * since users shoudl not try to modify returned data. Signed-off-by: Dmitry Torokhov Signed-off-by: Greg Kroah-Hartman
