Subject: [dpdk-stable] [PATCH] eal: fix unitialized data warning
Date: Wed, 27 Nov 2019 14:32:32 -0800
Message-ID: <20191127223232.26404-1-stephen@networkplumber.org> (raw)

Valgrind reports that eal interrupt thread is calling epoll_ctl
with uninitialized data.  Trivial to fix by initializing it.

Fixes: af75078fece3 ("first public release")
Cc: stable@dpdk.org
Signed-off-by: Stephen Hemminger <stephen@networkplumber.org>
