From b692f7d1576baf961fa02f681658640ac4edca92 Mon Sep 17 00:00:00 2001 From: Naohiro Aota Date: Tue, 8 Aug 2023 01:12:40 +0900 Subject: [PATCH] btrfs: zoned: re-enable metadata over-commit for zoned mode commit 5b135b382a360f4c87cf8896d1465b0b07f10cb0 upstream. Now that, we can re-enable metadata over-commit. As we moved the activation from the reservation time to the write time, we no longer need to ensure all the reserved bytes is properly activated. Without the metadata over-commit, it suffers from lower performance because it needs to flush the delalloc items more often and allocate more block groups. Re-enabling metadata over-commit will solve the issue.
