No, you can't do this, since the blkstart will be used for dc->lstart. So, it needs to do like this? >From 01cfee96f3568590ba58f6d2b36150dce7054491 Mon Sep 17 00:00:00 2001 From: Jaegeuk Kim <jaeg...@kernel.org> Date: Tue, 7 Mar 2017 16:32:35 -0800 Subject: [PATCH] f2fs: fix the fault of calculating blkstart twice When the zone type is BLK_ZONE_TYPE_CONVENTIONAL, the blkstart is calculated twice.
