Merge tag 'for-6.10-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/kdave/linux

Pull more btrfs updates from David Sterba:
 "A few more updates, mostly stability fixes or user visible changes:

   - fix race in zoned mode during device replace that can lead to
     use-after-free

   - update return codes and lower message levels for quota rescan where
     it's causing false alerts

   - fix unexpected qgroup id reuse under some conditions

   - fix condition when looking up extent refs

   - add option norecovery (removed in 6.8), the intended replacements
     haven't been used and some aplications still rely on the old one

   - build warning fixes"
