Subject: [PATCH] mm/page_alloc.c: variable type of 'progress' should be 'unsigned long'
Date:   Tue, 15 Sep 2020 18:46:20 +0800

From: Yanfei Xu <yanfei.xu@windriver.com>

try_to_free_pages returns the number of pages reclaimed, and the type of
returns is 'unsigned long'. So we should use a matched type for storing
it.
