However, even with this commit, systemtap still can't find certain kernel tracepoint= s. There is a script, in src/scripts/tracepoint-diff that points this out. Here are the missing tracepoints, listed by OS.

I've debugged this issue somewhat, and the missing xfs tracepoints are beca= use we need to add a '-I DIR' gcc option to compiles. --=20 You are receiving this mail because: You are the assignee for the bug.
