From 3d8712265c26546823b38eb97487262500ff13db Mon Sep 17 00:00:00 2001 From: Brian Foster Date: Tue, 15 Jul 2014 07:41:37 +1000 Subject: xfs: add a sysfs kset Create a sysfs kset to contain all sub-objects associated with the XFS module. The kset is created and removed on module initialization and removal respectively. The kset uses fs_obj as a parent. This leads to the creation of a /sys/fs/xfs directory when the kset exists.
