Subject: [PATCH 0/2] btrfs: zoned: fix zone management on degraded filesystems
Date: Mon, 17 Mar 2025 12:24:57 +0100	[thread overview]
Message-ID: <cover.1742210138.git.jth@kernel.org> (raw)

Two fixes around ZONE FINISH and ZONE ACTIVATE for multi device filesystems in
degraded mode.

Both times we're dereferencing the btrfs_device::zone_info pointer without
prior checking if the device is present.

Johannes Thumshirn (2):
  btrfs: zoned: fix zone activation with missing devices
  btrfs: zoned: fix zone finishing with missing devices
