Created attachment 338784 [details] patch to add trace subdir to kernel-devel package Description of problem: AS part of my writing a script to emulate dropwatch via systemtap, I noted that I was not able to use kernel.trace probes or the stap -L option to list available probes. stap always returned a NULL search result (indicating no tracepoints available). The problem turns out to be that the kernel-devel package fails to include the include/trace subdirectory, so stap can't find any included probes. We need to include this to allow systemtap to properly use tracepoints in 5.4 How reproducible: Always Steps to Reproduce: 1. run stap -L 'kernel.trace("*")' Actual results: semantic error: no match while resolving probe point kernel.trace("*") Expected results: list of available tracepoints in the kernel Additional info:
