Subject: Silence bogus Coverity warning of uninitialized value
X-Git-Tag: v2.11.0-rc1~605
X-Git-Url: https://git.lttng.org/?p=lttng-tools.git;a=commitdiff_plain;h=1065191b50b33888c6cf5f359c73bd97ee21f0bb

Silence bogus Coverity warning of uninitialized value

Coverity complains that struct lttng_trigger_comm's
payload field is not initialized. "payload" is a flexible
array member which should be ignored. Normally, a such a
member _could_ result in additional padding added at the
end of the structure. In this case, the structure is declared
as packed.

Nonetheless, using a designated initializer gets rid of the
ambiguity and silences Coverity.
