From e7ff9e6b8e7d89199119468ae61b29a56f81ad28 Mon Sep 17 00:00:00 2001 From: Johannes Thumshirn Date: Wed, 19 May 2021 00:40:29 +0900 Subject: btrfs: zoned: factor out zoned device lookup To be able to construct a zone append bio we need to look up the btrfs_device. The code doing the chunk map lookup to get the device is present in btrfs_submit_compressed_write and submit_extent_page. Factor out the lookup calls into a helper and use it in the submission paths.
