[PATCH] tracing: Make hash-ptr option default

From: Steven Rostedt
Date: Fri Feb 12 2021 - 16:25:22 EST


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

Since the original behavior of the trace events is to hash the %p pointers,
make that the default, and have developers have to enable the option in
order to have them unhashed.
