From 25ebbce1f188aa2d3e83fcfcf24da8610362564b Mon Sep 17 00:00:00 2001 From: Joel Granados Date: Fri, 27 Jun 2025 10:00:51 +0200 Subject: kernel/sys.c: Move overflow{uid,gid} sysctl into kernel/sys.c Moved ctl_tables elements for overflowuid and overflowgid into in kernel/sys.c. Create a register function that keeps them under "kernel" and run it after core with postcore_initcall. This is part of a greater effort to move ctl tables into their respective subsystems which will reduce the merge conflicts in kernel/sysctl.c.
