Subject: [PATCH 4/6 v2] tools lib api fs: Add DEBUGFS_DEFAULT_PATH macro
Date: Mon, 02 Feb 2015 14:35:05 -0500 [thread overview]
Message-ID: <20150202193553.032117017@goodmis.org> (raw)
In-Reply-To: 20150202193501.962297539@goodmis.org
[-- Attachment #1: 0004-tools-lib-api-fs-Add-DEBUGFS_DEFAULT_PATH-macro.patch --]
[-- Type: text/plain, Size: 1220 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.
