4.17-stable review patch. If anyone has any objections, please let me know.
------------------ From: Cong Wang <[email protected]> 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.
