From 65b65735fede29b516fed1d8c2391e8bc373b805 Mon Sep 17 00:00:00 2001 From: Brian Foster Date: Tue, 9 Sep 2014 11:52:42 +1000 Subject: xfs: add debug sysfs attribute set Create a top-level debug directory for global debug sysfs attributes. This directory is added and removed on XFS module initialization and removal respectively for DEBUG mode kernels only. It typically resides at /sys/fs/xfs/debug. It is located at the top level of the xfs sysfs hierarchy as attributes might define global behavior or behavior that must be configured before an xfs mount is available (e.g., log recovery behavior). Define the global debug kobject that represents the debug sysfs directory and add generic attribute show/store helpers to support future attributes. No debug attributes are exported as of yet.
