Subject[PATCH v2 0/2] ACPI: container hot remove support.
Date
Hi,

The container hotplug handler container_notify_cb() didn't implement
the hot-remove functionality. So, these 2 patches implement it like
the following way:

patch 1. Do not use kacpid_wq/kacpid_notify_wq to handle container hotplug event,
use kacpi_hotplug_wq instead to avoid deadlock.
Doing this is to reuse acpi_bus_hot_remove_device() in container
hot-remove handling.

patch 2. Introduce a new function container_device_remove() to handle
ACPI_NOTIFY_EJECT_REQUEST event for container.


change log v1 -> v2:

1. In patch1: Based on the lastest for-pci-split-pci-root-hp-2 branch from Lu Yinghai,
use alloc_acpi_hp_work() to add container hotplug work into kacpi_hotplug_wq.

2. In patch2: Allocate ej_event after container is stopped, so that we don't need to
kfree the ej_event if stopping container failed.


This is based on Lu Yinghai's job.

Tang Chen (2):
Use kacpi_hotplug_wq to handle container hotplug event.
Improve container_notify_cb() to support container hot-remove.
