Subject: scsi: core: Introduce scsi_get_sector()
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=f0f214fe8cd32224267ebea93817b8c32074623d;p=linux.git

scsi: core: Introduce scsi_get_sector()

Since scsi_get_lba() returns a sector_t value instead of the LBA, the name
of that function is confusing. Introduce an identical function
scsi_get_sector().
