From 7fe063268e73681cdca1a6496a25f93d3332f517 Mon Sep 17 00:00:00 2001 From: Andrew Patterson Date: Tue, 2 Jun 2009 14:48:39 +0200 Subject: cciss: add cciss driver sysfs entries Add sysfs entries to the cciss driver needed for the dm/multipath tools. A file for vendor, model, rev, and unique_id is added for each logical drive under directory /sys/bus/pci/devices//ccissX/cXdY. Where X = the controller (or host) number and Y is the logical drive number. A link from /sys/bus/pci/devices//ccissX/cXdY/block:cciss!cXdY to /sys/block/cciss!cXdY/device is also created. A bus is created in /sys/bus/cciss. A link is created from the pci ccissX entry to /sys/bus/cciss/devices/ccissX. Please consider this for inclusion. Signed-off-by: Mike Miller Cc: Stephen M.
