Subject: [GIT PULL] Backing device changes for 3.20
Hi Linus,
This pull request contains a cleanup of how the backing device is
handled, in preparation for a rework of the life time rules. In this
part, the most important change is to split the unrelated nommu mmap
flags from it, but also removing a backing_dev_info pointer from the
address_space (and inode), and a cleanup of other various minor bits.
Christoph did all the work here, I just fixed an oops with pages that
have a swap backing. Arnd fixed a missing export, and Oleg killed the
lustre backing_dev_info from staging. Last patch was from Al,
unexporting parts that are now no longer needed outside.
Please pull!
