From aef9d25e7f5631543a0276d0532151f2c61174d6 Mon Sep 17 00:00:00 2001 From: Joel Granados Date: Tue, 4 Jun 2024 08:29:23 +0200 Subject: sysctl: Remove superfluous empty allocations from sysctl internals Now that the sentinels have been removed from ctl_table arrays, there is no need to artificially append empty ctl_table elements at ctl_table registration. Remove superfluous empty allocation from new_dir and new_links.
