Since the fsverity sysctl registration runs as a builtin initcall, there is no corresponding sysctl deregistration and the resulting struct ctl_table_header is not used. This can cause a kmemleak warning just after the system boots up. (A pointer to the ctl_table_header is stored in the fsverity_sysctl_header static variable, which kmemleak should detect; however, the compiler can optimize out that variable.) Avoid the kmemleak warning by using register_sysctl_init() which is intended for use by builtin initcalls and uses kmemleak_not_leak().
