From 6a8ebc773ef64c8f12d6d60fd6e53d5ccc81314b Mon Sep 17 00:00:00 2001 From: Naohiro Aota Date: Tue, 8 Aug 2023 01:12:38 +0900 Subject: btrfs: zoned: no longer count fresh BG region as zone unusable Now that we switched to write time activation, we no longer need to (and must not) count the fresh region as zone unusable. This commit is similar to revert of commit fa2068d7e922b434eb ("btrfs: zoned: count fresh BG region as zone unusable").
