Author: ngie Date: Tue Jan 19 01:33:27 2016 New Revision: 294301 URL: https://svnweb.freebsd.org/changeset/base/294301 Log: MFstable/10 r294300: MFC r293715: Fix a mismerge from NetBSD in r162194 with `xdr_rpcb_entry_list_ptr(..)` This fixes the potential NULL pointer dereference properly, and also fixes memory leaks encountered in the process of iterating through `*rp`.
