From eea3e8b74aa1648fc96b739458d067a6e498c302 Mon Sep 17 00:00:00 2001 From: Kemeng Shi <shikemeng@huawei.com> Date: Mon, 5 Dec 2022 19:57:09 +0800 Subject: [PATCH] blk-throttle: Use more suitable time_after check for update of slice_start There is no need to update tg->slice_start[rw] to start when they are equal already. So remove "eq" part of check before update slice_start.
