Subject: [Patch v5 0/4] cleanup on do_pages_move()
Date:   Fri, 14 Feb 2020 08:30:13 +0800
Message-Id: <20200214003017.25558-1-richardw.yang@linux.intel.com>

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.

v5:
  : rebase on top of latest upstream, "linux/pipe_fs_i.h: fix kernel-doc
    warnings after @wait was split"
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()
