[Patch v4 0/4] cleanup on do_pages_move()

From: Wei Yang
Date: Wed Jan 29 2020 - 17:16:31 EST


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.

v4:
* rephrase changelog based on suggestion from David Hildenbrand
* trivial change on code style and comment
v3:
* rebase on top of Yang Shi's fix "mm: move_pages: report the number of
non-attempted pages"
v2:
* remove some unnecessary cleanup

Wei Yang (4):
mm/migrate.c: no need to check for i > start in do_pages_move()
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: unify "not queued for migration" handling in
do_pages_move()
