From 52f7c21b613f80cb425d115c9e5b4ed958a133c0 Mon Sep 17 00:00:00 2001 From: Mark Fasheh Date: Tue, 29 Jan 2008 17:08:26 -0800 Subject: ocfs2: Move /sys/o2cb to /sys/fs/o2cb /sys/fs is where we really want file system specific sysfs objects. Ocfs2-tools has been updated to look in /sys/fs/o2cb. We can maintain backwards compatibility with old ocfs2-tools by using a sysfs symlink. After some time (2 years), the symlink can be safely removed. This patch also adds documentation to make it easier for people to figure out what /sys/fs/o2cb is used for.
