Subject: [PATCH v2 7/8] ia64: Remove now superfluous sentinel element from ctl_table array
Date: Wed, 13 Sep 2023 11:11:01 +0200 [thread overview]
Message-ID: <20230913-jag-sysctl_remove_empty_elem_arch-v2-7-d1bd13a29bae@samsung.com> (raw)
In-Reply-To: <20230913-jag-sysctl_remove_empty_elem_arch-v2-0-d1bd13a29bae@samsung.com>
From: Joel Granados <j.granados@samsung.com>
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 kdump_ctl_table. This removal is safe because
register_sysctl implicitly uses ARRAY_SIZE() in addition to checking for
the sentinel.
