Subject: [RFC 00/11] make try_to_unmap simple

Currently, try_to_unmap returns various return value(SWAP_SUCCESS,
SWAP_FAIL, SWAP_AGAIN, SWAP_DIRTY and SWAP_MLOCK). When I look into
that, it's unncessary complicated so this patch aims for cleaning
it up. Change ttu to boolean function so we can remove SWAP_AGAIN,
SWAP_DIRTY, SWAP_MLOCK.

This patchset is based on v4.10-mmots-2017-02-28-17-33.

Minchan Kim (11):
  mm: use SWAP_SUCCESS instead of 0
  mm: remove unncessary ret in page_referenced
  mm: remove SWAP_DIRTY in ttu
  mm: remove SWAP_MLOCK check for SWAP_SUCCESS in ttu
  mm: make the try_to_munlock void function
  mm: remove SWAP_MLOCK in ttu
  mm: remove SWAP_AGAIN in ttu
  mm: make ttu's return boolean
  mm: make rmap_walk void function
  mm: make rmap_one boolean function
  mm: remove SWAP_[SUCCESS|AGAIN|FAIL]
