From 3bc269cfd3e119be84b69d95aec3a9e147016bb2 Mon Sep 17 00:00:00 2001 From: Joel Granados Date: Wed, 9 Aug 2023 12:49:59 +0200 Subject: sysctl: Add size arg to __register_sysctl_init This commit adds table_size to __register_sysctl_init in preparation for the removal of the sentinel elements in the ctl_table arrays (last empty markers). And though we do *not* remove any sentinels in this commit, we set things up by calculating the ctl_table array size with ARRAY_SIZE. We add a table_size argument to __register_sysctl_init and modify the register_sysctl_init macro to calculate the array size with ARRAY_SIZE. The original callers do not need to be updated as they will go through the new macro.
