Subject: Clean-up: relayd send_command() helper is not const-correct
X-Git-Tag: v2.11.0-rc1~364
X-Git-Url: https://git.lttng.org./?a=commitdiff_plain;h=76b9afaa436496319456775d7ba7f20eeac09d5d;p=lttng-tools.git

Clean-up: relayd send_command() helper is not const-correct

The payload sent to the relayd as part of a command is not
expected to be modified when it is sent. This commit makes
the data parameter 'const' to enforce this assumption.
