Subject: Fix: unchecked return value of cds_lfht_destroy
X-Git-Tag: v2.11.0-rc1~142
X-Git-Url: https://git.lttng.org./?a=commitdiff_plain;h=8aca663cd2a1cc1680b18a349f7d8b9bef8ef490;p=lttng-tools.git

Fix: unchecked return value of cds_lfht_destroy

The sessiond should assert that cds_lfht_destroy returns 0 when
tearing down the 'pending rotate channel' hash table as a non-zero
value would indicate a leak.
