Subject: zram: use proper type to update max_used_pages
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=2ea55a2caee016daee511431217861fb04767b27;p=linux-beck.git

zram: use proper type to update max_used_pages

max_used_pages is 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 a 64 bit system.
