When using -Wextra, gcc complains about torture_preempt_schedule() when its definition is empty (i.e., when CONFIG_PREEMPTION is not set/enabled). Fix these warnings by adding an empty do-while block for that macro when CONFIG_PREEMPTION is not set. Fixes these build warnings: ../kernel/locking/locktorture.c:119:29: warning: suggest braces around empty body in an ‘if’ statement [-Wempty-body] ../kernel/locking/locktorture.c:166:29: warning: suggest braces around empty body in an ‘if’ statement [-Wempty-body] ../kernel/locking/locktorture.c:337:29: warning: suggest braces around empty body in an ‘if’ statement [-Wempty-body] ../kernel/locking/locktorture.c:490:29: warning: suggest braces around empty body in an ‘if’ statement [-Wempty-body] ../kernel/locking/locktorture.c:528:29: warning: suggest braces around empty body in an ‘if’ statement [-Wempty-body] ../kernel/locking/locktorture.c:553:29: warning: suggest braces around empty body in an ‘if’ statement [-Wempty-body] I have verified that there is no object code change (with gcc 7.5.0).
