From e3b3e2e847080e3cc14bee778c6ced3d59bfd76c Mon Sep 17 00:00:00 2001 From: "Steven Rostedt (Red Hat)" Date: Mon, 11 Nov 2013 23:07:14 -0500 Subject: [PATCH] ftrace: Pass in global_ops for use with filtering files 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.
