From 433d4b03e722bdfb1b6a75563cb45e8dca6784e7 Mon Sep 17 00:00:00 2001 From: Kemeng Shi Date: Mon, 16 Jan 2023 17:51:51 +0800 Subject: [PATCH] block, bfq: remove redundant check in bfq_put_cooperator We have already avoided a circular list in bfq_setup_merge (see comments in bfq_setup_merge() for details), so bfq_queue will not appear in it's new_bfqq list. Just remove this check.
