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
