There are a few places that use bdev->bd_inode. They don't need to
anymore as they can use the bdev file and bdev_file_inode().

Most of these really should be using proper high level APIs.  The
last round of work on this is here:

Are you saying that I should just drop this patch here?

I think we need to order the work:

 - get your use struct file as bdev handle series in
 - rebase the above series on top of that, including some bigger changes
   like block2mtd which can then use normal file read/write APIs
 - rebase what is left of this series on top of that, and hopefully not
   much of this patch and a lot less of patch 1 will be left at that
   point.

I'm working on that now, mostly convert to use bdev_file, and file_inode
or f_mapingo

I'm working on that now, mostly convert to use bdev_file, and file_inode
to get 'bd_inode' or f_mapping to get 'bd_inode->f_mapping', and now
that all fs and all drivers can avoid to access 'bd_inode' now.

This is done by a huge patch for now, and there really is nothing left
of this set. I'm still testing and spliting into a patchset. I'll post a
RFC version soon.

Thanks,
Kuai
