Subject: [PATCH 08/10] fs/cachefiles/: convert to parse_integer()
Date: Sat, 2 May 2015 03:59:01 +0300 [thread overview]
Message-ID: <20150502005901.GH21655@p183.telecom.by> (raw)
In-Reply-To: <20150502004714.GA21655@p183.telecom.by>
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. :^)
