Override the PY_CMD_ESCAPED as the PY_CMD_ESCAPED is constructed by
the full path of the python3. In some cases, the path is so long and
result in the PY_CMD_ESCAPED exceeds 255 characters and comes below

Exception ignored on calling ctypes callback function:
<function PerfEventArray.open_perf_buffer.<locals>.raw_cb at 0x7f7c9efea280>
Traceback (most recent call last):
File "/usr/lib64/python3.8/site-packages/bcc/table.py", line 685, in raw_cb_
callback(cpu, data, size)
File "/usr/share/bcc/tools/trace", line 630, in print_event

raise SystemExit(code)
SystemExit: None
Class Probe::print_event is used as a callback of a ctypes wrapper. With
Yocto latest python v3.8.5, the exception raised by exit() is ignored and
thus trace cannot exit. Use os._exit(0) instead.

/usr/share/bcc/tools/biosnoop
cannot attach kprobe, probe entry may not exist
Traceback (most recent call last):
File "/usr/share/bcc/tools/biosnoop", line 162, in <module>
b.attach_kprobe(event="blk_account_io_completion",
File "/usr/lib64/python3.8/site-packages/bcc/_init_.py", line 660, in attach_kprobe
raise Exception("Failed to attach BPF program %s to kprobe %s" %
Exception: Failed to attach BPF program b'trace_req_completion' to kprobe b'blk_account_io_completion'
The kernel function "blk_account_io_completion" is not available anymore
as attach point of Kprobe as of kernel version 5.8.0. Therefore, after
discussions, we decided to use function "blk_account_io_done" instead in
every kprobe attachment to "blk_account_io_completion".
