From ade7db991b47ab3016a414468164f4966bd08202 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Fri, 2 Feb 2018 16:48:47 +0100 Subject: cifs: silence compiler warnings showing up with gcc-8.0.0 This bug was fixed before, but came up again with the latest compiler in another function: fs/cifs/cifssmb.c: In function 'CIFSSMBSetEA': fs/cifs/cifssmb.c:6362:3: error: 'strncpy' offset 8 is out of the bounds [0, 4] [-Werror=array-bounds] strncpy(parm_data->list[0].name, ea_name, name_len); Let's apply the same fix that was used for the other instances.
