Jim, I applied the patch but still nodwf01.stp and nodwf02.stp fails.

semantic error: no match while resolving probe point 
kernel.function("sys_pipe")
Pass 2: analysis failed.  Try again with more '-v' (verbose) options.

On searching sys_pipe in /proc/kallsyms, I got this.

[root@llm27lp1 src]# grep "sys_pipe" /proc/kallsyms
c0000000000fc410 W .sys_pipe2
c0000000000fc490 W .sys_pipe
