Subject: don't use ->bd_inode to access the block device size v3
Hi Jens,
various drivers currently poke directy at the block device inode, which
is a bit of a mess. This series cleans up the places that read the
block device size to use the proper helpers. I have separate patches
for many of the other bd_inode uses, but this series is already big
enough as-is,
Changes since v2:
- bdev_nr_bytes should return loff_t
- fix a commit message typo
- drop a redundant note in a commit message
Changes since v1:
- move SECTOR_SIZE & co
- use SECTOR_SHIFT in sb_bdev_nr_blocks
- add a bdev_nr_bytes helper
- reuse a variable in the SCSI target code
- drop the block2mtd patch, a bigger rewrite for that code is pending
