From 355958f2893d97375da17696d2566dd4ab7b54a8 Mon Sep 17 00:00:00 2001 From: "Eric W. Biederman" Date: Wed, 6 Feb 2013 00:10:23 -0800 Subject: cifs: Use BUILD_BUG_ON to validate uids and gids are the same size The assumption that sizeof(uid_t) is the same as sizeof(gid_t) is completely reasonable but since we can verify the condition at compile time.
