// FILE_FLAG_OPEN_REPARSE_POINT flag when opening the file if it is a reparse

	// And per https://learn.microsoft.com/en-us/windows/win32/api/fileapi/nf-fileapi-createfilew,
	// “If the file is not a reparse point, then this flag is ignored.”
	//
	// So we set FILE_FLAG_OPEN_REPARSE_POINT unconditionally, since we want
	// information about the reparse point itself.
