From b848914ce39589d89ee0078a6d1ef452b464729e Mon Sep 17 00:00:00 2001 From: Steven Rostedt Date: Wed, 4 May 2011 09:27:52 -0400 Subject: ftrace: Implement separate user function filtering ftrace_ops that are registered to trace functions can now be agnostic to each other in respect to what functions they trace. Each ops has their own hash of the functions they want to trace and a hash to what they do not want to trace. A empty hash for the functions they want to trace denotes all functions should be traced that are not in the notrace hash. Cc: Paul E.
