Commit Message

Arnd Bergmann March 4, 2019, 8:34 p.m. UTC 
When CONFIG_BPF_SYSCALL or CONFIG_SYSCTL is disabled, we get
a warning about an unused function:

kernel/sysctl.c:3331:12: error: 'proc_dointvec_minmax_bpf_stats' defined but not used [-Werror=unused-function]
 static int proc_dointvec_minmax_bpf_stats(struct ctl_table *table, int write,

The CONFIG_BPF_SYSCALL check was already handled, but the SYSCTL check
is needed on top.

Fixes: 492ecee892c2 ("bpf: enable program stats")
