[GIT PULL] Btrfs fixes for 6.8-rc4

[David Sterba <dsterba@suse.com>]

Hi,

please pull a few error handling fixes. Thanks.

- two fixes preventing deletion and manual creation of subvolume qgroup

- unify error code returned for unknown send flags

- fix assertion during subvolume creation when anonymous device could
  be allocated by other thread (e.g. due to backref walk)
