Hi, all, This patch series is for battery hotplug support. Please refer to http://bugzilla.kernel.org/show_bug.cgi?id=2884 Patch 01 flushes kacpi_notify_wq before removing the notify handler as well as the kacpid_wq. Patch 02 adds a new acpi execute type, OSL_DEVICE_HOTPLUG_HANDLER, This is used for the device hotplug notify handler which will be queued in keventd_wq so that it can flush the kacpi_notify_wq. Patch 03 support battery hotplug in the global system-level notify handler acpi_bus_notify. Patch 04 fix the deadlock when pokiing the "eject" sysfs attribute which is used to eject a device in user space. I've tested this patch set on my t43 laptop and it works well. Any comment is appreciated. :) Thanks, Rui - To unsubscribe from this list: send the line "unsubscribe linux-acpi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
