[PATCH] bdev: add I_BDEV()
From: viro@parcelfarce.linux.theplanet.co.uk <viro@parcelfarce.linux.theplanet.co.uk>
For bdevfs inodes (ones created along with struct block_device by
fs/block_dev.c) we have inode->i_bdev equal to &BDEV_I(inode)->bdev (i.e.
it's at the constant offset from inode). New helper added for such inodes
(I_BDEV(inode)). A bunch of places (mostly in block_dev.c) switched to use
of that helper. A bunch of places that used
file->f_dentry->d_inode->i_bdev->bd_inode
switched to
file->f_mapping->host
- those expressions are equal whenever the former is valid.
