Subject: [PATCH 01/05] use proc_dointvec_minmax to check boundaries while needed
Date: Thu, 3 Mar 2011 21:58:20 +0800 [thread overview]
Message-ID: <20110303135819.GA2620@darkstar> (raw)
proc_dointvec doesn't check extra minmax params, use proc_dointvec_minmax
instead of proc_dointvec for cases need boundaries check.
