From c7227e46423a57b4df27a2d75b5869bd3ae654d0 Mon Sep 17 00:00:00 2001 From: Bob Peterson Date: Fri, 2 Nov 2007 09:37:15 -0500 Subject: [PATCH] [GFS2] Given device ID rather than s_id in "id" sysfs file This patch changes the /sys/fs/gfs2//id file to give the device id "major:minor" rather than the s_id. That enables gfs2_tool to match devices properly (by id, not name) when locating the tuning files.
