4.17-stable review patch. If anyone has any objections, please let me know.
------------------
From: Cong Wang <xiyou.wangc...@gmail.com>
commit 8b2ebb6cf064247d60cccbf1750610ac9bb2e672 upstream.
Similarly, tbl->entries is not initialized after kmalloc(),
therefore causes an uninit-value warning in ip_vs_lblc_check_expire(),
as reported by syzbot.
