Subject: [GIT PULL] Btrfs fixes for 5.10-rc6

Hi,

a few fixes for various warnings that accumulated over past two weeks.

- tree-checker: add missing return values for some errors

- lockdep fixes
  - when reading qgroup config and starting quota rescan
  - reverse order of quota ioctl lock and VFS freeze lock

- avoid accessing potentially stale fs info during device scan,
  reported by syzbot

- add scope NOFS protection around qgroup relation changes

- check for running transaction before flushing qgroups

- fix tracking of new delalloc ranges for some cases

Please pull, thanks.
