Subject: tools lib traceevent: Fix memory leak in pretty_print()
From: Steven Rostedt <rostedt@xxxxxxxxxxx>
commit de04f8657de9d3351a2d5880f1f7080b23b798cf upstream.
Commit 12e55569a244 "tools lib traceevent: Use helper trace-seq in print
functions like kernel does" added a extra trace_seq helper to process
string arguments like the kernel does it. But the difference between the
kernel and the userspace library is that the kernel's trace_seq structure
has a static allocated buffer. The userspace one has a dynamically
allocated one. It requires a trace_seq_destroy(), otherwise it produces
a nasty memory leak.
