[PATCH] kernel/module: Use BUG_ON instead of if condition followed by BUG.

Usually, the condition in if () is not satisfied. For the multi-stage pipeline, we do not need to perform fetch decode and excute operation on brk instruction. In my opinion, this can improve the efficiency of the multi-stage pipeline. Signed-off-by: zhouchuangao --- kernel/module.c | 4 ++-- 1
