Sometimes Callback File System completes I/O without callback calls. In this case, the completion status is FILE INVALID (I don't know what this error code is but procmon.exe shows.) This is ultimate hard error. So I want to know about Callback File System's own I/O completion rules as exactly as possible, that occurs FILE INVALID error. Thanks.

Hello Gyuho,

CallbackFS completes requests to files with STATUS_FILE_INVALID when the user callbacks can't be called. This occurs when either a virtual storage was dismounted (i.e. UnmountMedia had been called) or a process, where the callbacks are implemented, was terminated.

It doesn't.
