nilfs2: An unassigned variable is assigned to a never used structure member
nilfs2: In procedure 'nilfs_get_sb()', when a nilfs filesysttem is mounted for the first time, local variable 'nilfs->ns_last_cno' is used before loading the latest checkpoint number from disk (in 'nilfs_fill_super'). 'nilfs->ns_last_cno' is assigned to 'sd.cno', but 'sd.cno' has never been used in the procedure.
