Subject: [PATCH AUTOSEL 4.19 07/25] f2fs: fix min_seq_blocks can not make sense in some scenes.
Date: Thu, 9 Sep 2021 20:22:15 -0400 [thread overview]
Message-ID: <20210910002234.176125-7-sashal@kernel.org> (raw)
In-Reply-To: <20210910002234.176125-1-sashal@kernel.org>
From: Laibin Qiu <qiulaibin@huawei.com>
[ Upstream commit dc675a97129c4d9d5af55a3d7f23d7e092b8e032 ]
F2FS have dirty page count control for batched sequential
write in writepages, and get the value of min_seq_blocks by
blocks_per_seg * segs_per_sec(segs_per_sec defaults to 1).
But in some scenes we set a lager section size, Min_seq_blocks
will become too large to achieve the expected effect(eg. 4thread
sequential write, the number of merge requests will be reduced).
