Subject: Re: [PATCH v3 bpf-next 4/9] libbpf: add kprobe/uprobe attach API

Hi all,

I bisected a perf build error on ARMv7 to this patch:
libbpf.c: In function ‘perf_event_open_probe’:
libbpf.c:4112:17: error: cast from pointer to integer of different
size [-Werror=pointer-to-int-cast]
  attr.config1 = (uint64_t)(void *)name; /* kprobe_func or uprobe_path */
                 ^

Is this a known issue?
