From 7998df0b6407da65a0fe8325d6ff239c4e14ff7d Mon Sep 17 00:00:00 2001 From: Joel Granados <j.granados@samsung.com> Date: Thu, 28 Mar 2024 16:57:48 +0100 Subject: [PATCH] memory: remove the now superfluous sentinel element from ctl_table array 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 from all files under mm/ that register a sysctl table.
