Functions
uint64_t	load_nt_word (void *addr)
m_result_t	m_phlog_tornbit_check_consistency (m_phlog_tornbit_nvmd_t *nvmd, pcm_word_t *nvphlog, uint64_t *stable_tail)
	Check the consistency of the non-volatile log and find the consistent stable region starting from the head.
m_result_t	m_phlog_tornbit_format (pcm_storeset_t *set, m_phlog_tornbit_nvmd_t *nvmd, pcm_word_t *nvphlog, int type)
	Formats the non-volatile physical log for reuse.
m_result_t	m_phlog_tornbit_alloc (m_phlog_tornbit_t **phlog_tornbitp)
	Allocates a volatile log structure.
m_result_t	m_phlog_tornbit_init (m_phlog_tornbit_t *phlog, m_phlog_tornbit_nvmd_t *nvmd, pcm_word_t *nvphlog)
	Initializes the volatile log descriptor using the non-volatile metadata referenced by log_dsc.
m_result_t	m_phlog_tornbit_truncate_async (pcm_storeset_t *set, m_phlog_tornbit_t *phlog)
	Truncates the log up to the read_index point.
void	m_phlog_print_buffer (m_phlog_tornbit_t *log)
