Date: Wed, 6 Mar 2013 16:38:06 -0300 Message-Id: <1362598686-3933-1-git-send-email-raphael.scarv@gmail.com> X-Mailer: git-send-email 1.7.2.5 Sender: linux-kernel-owner@vger.kernel.org List-ID: X-Mailing-List: linux-kernel@vger.kernel.org This patch removes BITS_PER_PAGE from pid_namespace.c and put it into pid_namespace.h instead, since we can simplify the define PID_MAP_ENTRIES by using the BITS_PER_PAGE.
