[PATCH 0/3] nodemask: align nodes_and{,not} with underlying bitmap ops

Posted by Yury Norov 3 weeks, 2 days ago

nodes_and{,not} are void despite that underlying bitmap_and(,not) return
boolean, true if the result bitmap is non-empty. Align nodemask API, and
simplify client code.

Yury Norov (3):
  nodemask: propagate boolean for nodes_and{,not}
  mm: use nodes_and() return value to simplify client code
  cgroup: use nodes_and() output where appropriate
