4.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Arnaldo Carvalho de Melo <acme@redhat.com>
commit d64b721d27aef3fbeb16ecda9dd22ee34818ff70 upstream.
The implicit fall through case label here is intended, so let us inform that to gcc >= 7:
util/strfilter.c: In function 'strfilter_node__sprint': util/strfilter.c:270:6: error: this statement may fall through [-Werror=implicit-fallthrough=] if (len < 0) ^ util/strfilter.c:272:2: note: here case '!': ^~~~ cc1: all warnings being treated as errors
