From 720ba12620ee09dce269adf4ad50958adac7bb54 Mon Sep 17 00:00:00 2001 From: Tejun Heo Date: Wed, 31 May 2006 18:28:13 +0900 Subject: [PATCH] libata-hp: update unload-unplug Update unload unplug - driver unloading / PCI removal. This is done by ata_port_detach() which short-circuits EH, disables all devices and freezes the port. With this patch, EH and unloading/unplugging are properly synchronized.
