[PATCH 4/8] x86 vdso: rm sentinel element from ctl_table array

From: Joel Granados via B4 Relay <devnull+j.granados.samsung.com@kernel.org>
Date: 2023-09-06 10:04:21
Also in: b4-sent, linux-fsdevel, linux-riscv, linux-s390, linuxppc-dev, lkml
Subsystem: the rest, x86 architecture (32-bit and 64-bit), x86 entry code, x86 vdso · Maintainers: Linus Torvalds, Thomas Gleixner, Ingo Molnar, Borislav Petkov, Dave Hansen, Andy Lutomirski

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.
