Subject: [PATCH 3/5] tools lib api fs: Add DEBUGFS_DEFAULT_PATH macro
Date: Sat, 24 Jan 2015 13:13:33 -0500	[thread overview]
Message-ID: <20150124181448.835464482@goodmis.org> (raw)
In-Reply-To: <20150124181330.195149364@goodmis.org>

[-- Attachment #1: 0003-tools-lib-api-fs-Add-DEBUGFS_DEFAULT_PATH-macro.patch --]
[-- Type: text/plain, Size: 1239 bytes --]

From: "Steven Rostedt (Red Hat)" <rostedt@goodmis.org>

Instead of hard coding "/sys/kernel/debug" everywhere, create
a macro to hold where the default path exists.
