Error caused when running biotop or biosnoop.

Traceback (most recent call last):
  File "/usr/sbin/biosnoop-bpfcc", line 159, in <module>
    if BPF.get_kprobe_functions(b'blk_start_request'):
  File "/usr/lib/python3/dist-packages/bcc/__init__.py", line 539, in get_kprobe_functions
    with open("%s/../kprobes/blacklist" % TRACEFS, "rb") as blacklist_f:
PermissionError: [Errno 1] Operation not permitted: '/sys/kernel/debug/tracing/../kprobes/blacklist'

Fixed by removing the following lines at 539 in /usr/lib/python3/dist-packages/bcc/__init__.py

@staticmethod
    def get_kprobe_functions(event_re):
        #with open("%s/../kprobes/blacklist" % TRACEFS, "rb") as blacklist_f:
