    dax: give DAX clearing code correct bdev · 20a90f58
    Ross Zwisler 提交于
    dax_clear_blocks() needs a valid struct block_device and previously it
    was using inode->i_sb->s_bdev in all cases.  This is correct for normal
    inodes on mounted ext2, ext4 and XFS filesystems, but is incorrect for
    DAX raw block devices and for XFS real-time devices.
    
    Instead, rename dax_clear_blocks() to dax_clear_sectors(), and change
    its arguments to take a bdev and a sector instead of an inode and a
    block.  This better reflects what the function does, and it allows the
    filesystem and raw block device code to pass in an appropriate struct
    block_device.
