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 mm/migrate.c | 57 +++++++++++++++++++++++++++------------------------- 1 file changed, 30 insertions(+), 27 deletions(-) -- 2.17.1
