Subject: [PATCH 0/4] shmem: radix-tree cleanups and swapoff optimizations

Here some shmem patches related to the radix-tree iterator patchset,
they cleans radix-tree usage in shmem and notably optimizes swapoff operation.
Last patch is slightly off-topic, but it shares test results with previous patch.

Konstantin Khlebnikov (4):
      shmem: simlify shmem_unlock_mapping
      shmem: tag swap entries in radix tree
      shmem: use radix-tree iterator in shmem_unuse_inode()
      mm: use swap readahead at swapoff
