Commit Message

Daejun Park April 25, 2023, 8:10 a.m. UTC
Changelog:

v1 -> v2
Changed to apply the optional async reset write pointer by default.


This patch enables submit reset zone command asynchornously. It helps
decrease average latency of write IOs in high utilization scenario by
faster checkpointing.

If device doesn't support discard, it's better not show above tracepoint?

Can we call __submit_zone_reset_cmd() directly?

I refactored this function as follows.

static void __queue_zone_reset_cmd(struct f2fs_sb_info *sbi,
		struct block_device *bdev, block_t blkstart, block_t lblkstart,
		block_t blklen)
{
	trace_f2fs_queue_reset_zone(bdev, blkstart);

	mutex_lock(&SM_I(sbi)->dcc_info->cmd_lock);
	__insert_discard_cmd(sbi, bdev, lblkstart, blkstart, blklen);
	mutex_unlock(&SM_I(sbi)->dcc_info->cmd_lock);
}

This issue was caused by a mistake during the merge process. I have fixed it.

Sure. I refactored as follows.

	if (dc) {
		if (f2fs_sb_has_blkzoned(sbi) && bdev_is_zoned(dc->bdev)) {
			if (dc->state == D_PREP)
				__submit_zone_reset_cmd(sbi, dc, REQ_SYNC,
							&dcc->wait_list, NULL);
			dc->ref++;
			need_wait = true;
		} else {
			if (dc->state == D_PREP) {
				__punch_discard_cmd(sbi, dc, blkaddr);
			} else {
				dc->ref++;
				need_wait = true;
			}
		}
	}
