The patch titled
Subject: kernel/sysctl.c: fix unused function warning
has been removed from the -mm tree. Its filename was
sysctl-fix-unused-function-warning.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
From: Arnd Bergmann <arnd@xxxxxxxx>
Subject: kernel/sysctl.c: fix unused function warning
The newly added bpf_stats_handler() has the wrong #ifdef check around it,
leading to an unused-function warning when CONFIG_SYSCTL is disabled:
kernel/sysctl.c:205:12: error: unused function 'bpf_stats_handler' [-Werror,-Wunused-function]
static int bpf_stats_handler(struct ctl_table *table, int write,
Fix the check to match the reference.
