From 6c3864e055486fadb5b97793b57688082e14b43b Mon Sep 17 00:00:00 2001 From: Christoph Hellwig hch@lst.de Date: Mon, 4 Nov 2024 07:26:32 +0100 Subject: [PATCH] btrfs: use bio_is_zone_append() in the completion handler
Otherwise it won't catch bios turned into regular writes by the block level zone write plugging. The additional test it adds is for emulated zone append.
