I put suppression rules on\nthem so that we can run the checks, but some action must be taken for\n20.02 if my analysis is confirmed.\n\nSpecial thanks to Dodji the libabigail maintainer for helping on this\ntopic.\n\n1: https://sourceware.org/bugzilla/show_bug.cgi?id=25409\n2: http://inbox.dpdk.org/dev/CAJFAV8yFKoDZROX9Mkyp7pDMvXw3e7mHwxjfrcjD5ZoFB2tZ8w@mail.gmail.com/" }
