From c550e25bca660ed2554cbb48d32b82d0bb98e4b1 Mon Sep 17 00:00:00 2001 From: Jaegeuk Kim Date: Mon, 18 Apr 2022 16:57:44 -0700 Subject: [PATCH] f2fs: use flush command instead of FUA for zoned device The block layer for zoned disk can reorder the FUA'ed IOs. Let's use flush command to keep the write order.
