Subject: [Patch v2 0/4] cleanup on do_pages_move()
Date:   Wed, 22 Jan 2020 09:16:43 +0800

Precedence: bulk

The logic in do_pages_move() is a little mess for audience to read and has
some potential error on handling the return value. Especially there are
three calls on do_move_pages_to_node() and store_status() with almost the
same form.

This patch set tries to make the code a little friendly for audience by
consolidate the calls.

After this, we can do a better fix.

v2:
  * remove some unnecessary cleanup

Wei Yang (4):
  mm/migrate.c: not necessary to check start and i
  mm/migrate.c: wrap do_move_pages_to_node() and store_status()
  mm/migrate.c: check pagelist in move_pages_and_store_status()
  mm/migrate.c: handle same node and add failure in the same way
