This mini-series simplifies aims to zswap_swapoff(), which should
simplify in progress work touching it (zswap tree split, rbtree to
xarray conversion).

Patch 1 is a code readability change in the core swap code that makes
patch 2 (the actual simplification) more obviously correct.

Yosry Ahmed (2):
  mm: swap: update inuse_pages after all cleanups are done
  mm: zswap: remove unnecessary tree cleanups in zswap_swapoff()
