This patch series renames "sd_format_disk_name()" to "disk_name_format()" and moves it into block core. So that who needs formatting disk name can use it, instead of duplicating these similar help functions. Ren Mingxin (4): block: add function disk_name_format() into block core scsi: replace sd_format_disk_name() to disk_name_format() block: replace
