From: Joel Granados <redacted> 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/ (local)) Remove sentinel element from abi_table2. This removal is safe because register_sysctl implicitly uses ARRAY_SIZE() in addition to checking for the sentinel.
