Subject: [PATCH v2 0/5] clean up and generalize swap-over-NFS

Hi,

This patch series (based on ecb5ec0 in Linus' tree) contains all of the
non-BTRFS work that I've done to implement swapfiles on BTRFS. The BTRFS
portion is still undergoing development and is now outweighed by the
non-BTRFS changes, so I want to get these in separately.

Version 2 changes the generic swapfile interface to use ->read_iter and
->write_iter instead of using ->direct_IO directly in response to
discussion on the previous submission. It also adds the iov_iter_is_bvec
helper to factor out some common checks.

Version 1 can be found here: https://lkml.org/lkml/2014/12/15/7

Omar Sandoval (5):
  iov_iter: add ITER_BVEC helpers
  direct-io: don't dirty ITER_BVEC pages on read
  nfs: don't dirty ITER_BVEC pages read through direct I/O
  swapfile: use ->read_iter and ->write_iter
  vfs: update swap_{,de}activate documentation
