Subject: [PATCH] zram: use proper type to update max_used_pages
Date: Tue, 17 Feb 2015 14:26:38 +0900 [thread overview]
Message-ID: <1424150798-5547-1-git-send-email-iamjoonsoo.kim@lge.com> (raw)
max_used_pages are defined as atomic_long_t so we need to use
unsigned long to keep temporary value for it rather than int
which is smaller than unsigned long in 64 bit system.
