[for-next][PATCH 10/18] ftrace: Pass in global_ops for use with filtering files

From: Steven Rostedt
Date: Thu Feb 20 2014 - 21:53:31 EST


From: "Steven Rostedt (Red Hat)" <rostedt@xxxxxxxxxxx>

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.
