Subject: libust: remove process_simple_client_cmd function
X-Git-Tag: v1.9.1~420
X-Git-Url: https://git.lttng.org./?a=commitdiff_plain;h=1a9dbd91d1714133deacf8e531cd3bfcd443eb39;p=lttng-ust.git

libust: remove process_simple_client_cmd function

It was only used by one command, so move the command into
the big case statement and remove a now unnecessary function.

Spring cleaning.
