Subject: [RFC][PATCH v2 21/24] tools/lib/traceevent: Rename various pevent get/set/is APIs

From: "Tzvetomir Stoyanov (VMware)" <[email protected]>

In order to make libtraceevent into a proper library, variables, data
structures and functions require a unique prefix to prevent name space
conflicts. That prefix will be "tep_" and not "pevent_". This changes
APIs: pevent_pid_is_registered, pevent_get_cpus, pevent_set_cpus,
pevent_is_file_bigendian, pevent_is_host_bigendian, pevent_is_latency_format,
pevent_set_latency_format

Hi Arnaldo,

I'm curious to why the "(VMware)" part of my Signed-off-by was stripped
off on all these patches? It's required that is added to denote that my
work is done on my company time, otherwise I will have to use my vmware
email address which I really don't want to do.

I'll make sure it is kept, fixing my scripts,
