Subject: Warning fix: possible use of uninitialized variable
X-Git-Tag: v2.9.0-rc1~296
X-Git-Url: https://git.lttng.org./?a=commitdiff_plain;h=a905c62444dc13fa4547d3b86d5d0f3293fa7021;p=lttng-tools.git

Warning fix: possible use of uninitialized variable

GCC reports that discarded_events and lost_packets may be used
uninitialized. Assert that both pointers are not NULL to
silence the warning.
