From 8f6c5ffc8987f4f5b5a3e9d557d94bbf3a9bf216 Mon Sep 17 00:00:00 2001 From: Wang YanQing Date: Thu, 3 Apr 2014 14:48:26 -0700 Subject: kernel/groups.c: remove return value of set_groups After commit 6307f8fee295 ("security: remove dead hook task_setgroups"), set_groups will always return zero, so we could just remove return value of set_groups. This patch reduces code size, and simplfies code to use set_groups, because we don't need to check its return value any more.
