From 86ce18d7b7925bfd6b64c061828ca2a857ee83b8 Mon Sep 17 00:00:00 2001 From: Kristen Carlson Accardi Date: Wed, 23 May 2007 13:57:38 -0700 Subject: genhd: expose AN to user space Allow user space to determine if a disk supports Asynchronous Notification of media changes. This is done by adding a new sysfs file "capability_flags", which is documented in (insert file name). This sysfs file will export all disk capabilities flags to user space. We also define a new flag to define the media change notification capability.
