Subject: [PATCH lttng-tools] Fix: use newly created event filter for condition check
Date: Tue, 24 Sep 2019 10:53:16 -0400	[thread overview]
Message-ID: <20190924145316.21302-1-jonathan.rajotte-julien__10174.4646135316$1569336830$gmane$org@efficios.com> (raw)

4c5e3185d75ffe90b04107744693964d9051fb6b introduced a regression while
fixing the filter and filter_expression ownership.

Setting the "filter" object to NULL prevents the call to
add_filter_app_ctx when needed.

We use the filter from the newly created event to
perform the check and the call to add_filter_app_ctx.

Fixes coverity #1399733
