This commit comes at the tail end of a greater effort to remove the empty elements at the end of the ctl_table arrays (sentinels) which will reduce the overall build time size of the kernel and run time memory bloat by ~64 bytes per sentinel (further information Link : https://lore.kernel.org/all/ZO5Yx5JFogGi%2FcBo@bombadil.infradead.org/) * Remove sentinel element from ctl_table structs. * Remove the zeroing out of an array element (to make it look like a sentinel) in sysctl_route_net_init And ipv6_route_sysctl_init. This is not longer needed and is safe after commit c899710fe7f9 ("networking: Update to register_net_sysctl_sz") added the array size to the ctl_table registration. * Remove extra sentinel element in the declaration of devinet_vars. * Removed the "-1" in __devinet_sysctl_register, sysctl_route_net_init, ipv6_sysctl_net_init and ipv4_sysctl_init_net that adjusted for having an extra empty element when looping over ctl_table arrays * Replace the for loop stop condition in __addrconf_sysctl_register that tests for procname == NULL with one that depends on array size * Removing the unprivileged user check in ipv6_route_sysctl_init is safe as it is replaced by calling ipv6_route_sysctl_table_size; introduced in commit c899710fe7f9 ("networking: Update to register_net_sysctl_sz") * Use a table_size variable to keep the value of ARRAY_SIZE Signed-off-by: Joel Granados <j.granados@samsung.com> Signed-off-by: David S.
