每当我删除 gcsfuse 安装的文件系统上的文件时，该DeleteObject命令后面总是跟着一个UpdateObject命令，该命令会失败，因为该文件不再存在。删除本身会成功，无论是在本地还是在存储桶上，因此删除行为符合预期，但我想了解UpdateObject发送命令的原因，以及这是否只是预期行为，或者可能指向我这边的配置问题。以下是一些设置详细信息和日志摘录（敏感信息用“#”字符删除）：
gcsfuse 版本：0.40.0
安装命令： /usr/bin/gcsfuse --foreground --debug_fuse --debug_fs --debug_gcs --debug_http --debug_mutex --debug_invariants --log-file /home/###/gcsfuse.log ### /home/###/###
删除命令： rm deltest.txt
