From 0f4fc29dd68dfab9c6ddd5d087d34a5b6818cb00 Mon Sep 17 00:00:00 2001 From: Steven Rostedt Date: Wed, 20 May 2009 19:21:47 -0400 Subject: tracing: add __print_symbolic to trace events This patch adds __print_symbolic which is similar to __print_flags but works for an enumeration type instead. That is, there is only a one to one mapping between the values and the symbols. When a match is made, then it is printed, otherwise the hex value is outputed.
