In ee1d267423a1 ("pstore: add pstore unregister") I added: .owner = THIS_MODULE, in both pstore_fs_type and pstore_file_operations to increase a reference count when pstore filesystem is mounted and pstore file is opened. But, it's repetitive. There is no need to increase the opened reference count. We only need to increase the mounted reference count. When a file is opened, the filesystem can't be unmounted. Hence the pstore module can't be unloaded either. So I drop the opened reference count in this patch.
