Implement unload unplug - driver unloading / PCI removal via hot unplug path. This is done by ata_port_detach() which requests detach of all devices, schedules EH and wait for it to complete. EH path is slightly modified to handle this (e.g. force zero eh_info during unloading). With this patch, EH and unloading are properly synchronized and unloading should be safe under any circumstances. Signed-off-by: Tejun Heo <htejun@xxxxxxxxx>
How does this behave for controller hotplug? For that case, there is nothing to EH...
