Subject: [PATCH 4/6] block: stop setting the nomerges flags in blk_cleanup_queue
Date: Sun, 19 Jun 2022 08:05:50 +0200	[thread overview]
Message-ID: <20220619060552.1850436-5-hch@lst.de> (raw)
In-Reply-To: <20220619060552.1850436-1-hch@lst.de>

These flags only apply to file system I/O, and all file system I/O is
already drained by del_gendisk and thus can't be in progress when
blk_cleanup_queue is called.
