From: Joel Granados <j.granados@xxxxxxxxxxx> 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@xxxxxxxxxxxxxxxxxxxxxx/) * Remove sentinel element from ctl_table structs. * Remove extra element in ctl_table arrays declarations * Remove instances where an array element is zeroed out to make it look like a sentinel. 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 * Replace the for loop stop condition that tests for procname == NULL with one that depends on array size * Removed the "-1" that adjusted for having an extra empty element when looping over ctl_table arrays * 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") * Replace empty array registration with the register_net_sysctl_sz call.
