From 350e6e419902991b073b313aa65b240d1024d57e Mon Sep 17 00:00:00 2001 From: Cong Meng Date: Wed, 20 Jun 2012 14:47:10 +0800 Subject: scsi: introduce hotplug() and hot_unplug() interfaces for SCSI bus Add two interfaces hotplug() and hot_unplug() to scsi bus info. The scsi bus can implement these two interfaces to signal the HBA driver of guest kernel to add/remove the scsi device in question.
