Subjectlinux-next: build failure after merge of the bpf-next tree
Hi all,

After merging the bpf-next tree, today's linux-next build (arm
multi_v7_defconfig) failed like this:

kernel/sysctl.c:1238:13: error: 'sysctl_bpf_stats_enabled' undeclared here (not in a function); did you mean 'sysctl_base_table'?
.data = &sysctl_bpf_stats_enabled,
^~~~~~~~~~~~~~~~~~~~~~~~
sysctl_base_table

Caused by commit

492ecee892c2 ("bpf: enable program stats")

CONFIG_BPF=y
# CONFIG_BPF_SYSCALL is not set

I applied the following patch for today, but it should be done
properly. Also this patch leaves proc_dointvec_minmax_bpf_stats() as an
unused function.
