Subject: [PATCHv3 0/2] mm: use_mm/unuse_mm

This moves use_mm/unuse_mm from aio into mm, and optimizes atomic usage
there. Original patchset also exported use_mm/unuse_mm to modules, for
use by vhost, that bit will come in later when vhost is posted for
inclusion.

Michael S. Tsirkin (2):
  mm: move use_mm/unuse_mm from aio.c to mm/
  mm: reduce atomic use on use_mm fast path
