In the Linux kernel, the following vulnerability has been resolved: btrfs: fix anon_dev leak in create_subvol() When btrfs_qgroup_inherit(), btrfs_alloc_tree_block, or btrfs_insert_root() fail in create_subvol(), we return without freeing anon_dev. Reorganize the error handling in create_subvol() to fix this.
