DeleteObject с последующим UpdateObject

Question

Всякий раз, когда я удаляю файл в моей смонтированной файловой системе gcsfuse, DeleteObjectза командой всегда следует команда UpdateObject, которая не выполняется, потому что файл больше не существует. Само удаление выполняется успешно, как локально, так и в бакете, поэтому удаление ведет себя так, как и ожидалось, но я хотел бы понять, почему UpdateObjectотправляется команда, и является ли это просто ожидаемым поведением или, возможно, указывает на проблему конфигурации на моей стороне. Вот некоторые подробности настройки и выдержка из журнала (конфиденциальная информация отредактирована символами '#'):

версия gcsfuse:0.40.0

Команда монтирования: /usr/bin/gcsfuse --foreground --debug_fuse --debug_fs --debug_gcs --debug_http --debug_mutex --debug_invariants --log-file /home/###/gcsfuse.log ### /home/###/###

Команда удаления: rm deltest.txt
