Date:	Fri, 8 May 2015 21:37:51 +0300
From:	Alexey Dobriyan <adobriyan@...il.com>

Subject: [PATCH 10/37] parse_integer: convert fs/cachefiles/

Convert away from deprecated simple_strto*() interfaces.

Switch "unsigned long" to "unsigned int" where possible.
kstrto*() functions can't be used because of trailing "%" sign. :^)
