[PATCH 4/5] dm bufio: simplify by using PAGE_SECTORS_SHIFT

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The PAGE_SHIFT - SECTOR_SHIFT constant be replaced with PAGE_SECTORS_SHIFT
defined in linux/blt_types.h, which is included by linux/blkdev.h.

This produces no functional changes.
