Could I get the comments for the patch? thanks 在 2021/7/17 下午11:54, Xianting Tian 写道:
From: Xianting Tian <[email protected]>Ther is no unplugging timer now, on-stack io plugging is used: struct blk_plug plug; blk_start_plug(&plug); submit_batch_of_io(); blk_finish_plug(&plug); So remove the old comments for unplugging timer.
