楼主，我按照你的步骤安装一遍，最后运行cachetop和cachestat，报错：
bpf: Failed to load program: Invalid argument
Traceback (most recent call last):
File "./cachestat", line 97, in <module>
b.attach_kprobe(event="add_to_page_cache_lru", fn_name="do_count")
File "/usr/lib/python2.7/site-packages/bcc/__init__.py", line 630, in attach_kprobe
fn = self.load_func(fn_name, BPF.KPROBE)
File "/usr/lib/python2.7/site-packages/bcc/__init__.py", line 383, in load_func
(func_name, errstr))
Exception: Failed to load BPF program do_count: Invalid argument
BPF是什么鬼...
