lockdep_assert_held(&ctl->tree_lock);我们设置了用于加载可用空间缓存的临时可用空间 ctl以避免在加载缓存时发生分配。当我们遇到错误时我们会将其全部释放但是这也会调用 btrfs_discard_update_discardable而 btrfs_discard_update_discardable 需要保留 block_group->free_space_ctl->tree_lock。然而这是我们的临时 ctl因此未保持此锁定。通过调用 __btrfs_remove_free_space_cache_locked 来修复此问题以便我们仅清理条目并且不会混淆可丢弃的统计数据。 (CVE-2022-50571)
