From: Laibin Qiu <[email protected]> [ 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).
