問題如下：
$ stap main.stp -p3
semantic error: while resolving probe point: identifier 'kernel' at /usr/share/systemtap/tapset/linux/syscall_any.stp:18:21
source: probe syscall_any = kernel.trace("sys_enter")
^
semantic error: no match (similar tracepoints: user_enter, cpuhp_enter, ipi_entry, kfree, map)
semantic error: while resolving probe point: identifier 'syscall_any' at main.stp:1:7
source: probe syscall_any
^
semantic error: no match
Pass 2: analysis failed. [man error::pass2]
Tip: /usr/share/doc/systemtap/README.Debian should help you get started.
