Subject: [PATCH 2/8] mm profiling: Remove superfluous sentinel element from
 ctl_table

From: Joel Granados <j.granados@...sung.com>

This commit is part of a greater effort to remove all 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/)

Removed sentinel from memory_allocation_profiling_sysctls
