Subject: [PATCH v2 1/3] sched: fix confusing PFA_NO_NEW_PRIVS constant
Date: Mon, 22 Sep 2014 12:43:32 +0800 [thread overview]
Message-ID: <541FA8F4.90703@huawei.com> (raw)
Commit 1d4457f99928 ("sched: move no_new_privs into new atomic flags")
defined PFA_NO_NEW_PRIVS as hexadecimal value, but it is confusing
because it is used as bit number. Redefine it as decimal bit number.
Note this changes the bit position of PFA_NOW_NEW_PRIVS from 1 to 0.
