Subject: [PATCH] bpf: fix sysctl.c warning
Date: Mon,  4 Mar 2019 21:34:12 +0100	[thread overview]
Message-ID: <20190304203443.1992942-1-arnd@arndb.de> (raw)

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")
