Subject: [PATCH 5/8] sysctl: delete these duplicate static variables i_zero and i_one_hundred

From: Wen Yang <wenyang.linux@...mail.com>

Since these static variables (i_zero and i_one_hundred) are only used for
boundary checks and will not be changed, remove it and use the ones in
our shared const array.
