Regarding the tree-wide approach: there has already been a discussion about this on various kernel-related mailing lists. See also Linus Torvalds, Lots of new warnings with gcc-7.1.1, July 11, 2017 (https://www.mail-archive.com/netdev@xxxxxxxxxxxxxxx/msg177459.html). The conclusion was that certain of these warnings should be suppressed but that other warnings are useful and should be retained. See also commit bd664f6b3e37 ("disable new gcc-7.1.1 warnings for now"). Bart. ��.n��������+%������w��{.n�����{���fk��ܨ}���Ơz�j:+v�����w����ޙ��&�)ߡ�a����z�ޗ���ݢj��w�f
