Subject: [for-next][PATCH 10/18] ftrace: Pass in global_ops for use with filtering files
Date: Thu, 20 Feb 2014 21:49:16 -0500	[thread overview]
Message-ID: <20140221025002.536759736@goodmis.org> (raw)
In-Reply-To: 20140221024906.901631810@goodmis.org

[-- Attachment #1: 0010-ftrace-Pass-in-global_ops-for-use-with-filtering-fil.patch --]
[-- Type: text/plain, Size: 1729 bytes --]

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

In preparation for having the function tracing instances be able to
filter on functions, the generic filter functions must first be
converted to take in the global_ops as a parameter.
