Bug ID: 28394
Summary: Systemtap 4.6 on Centos 8.4/4.18 kernel died in
nfsd-trace example
Product: systemtap
Version: unspecified
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: runtime
Assignee: systemtap at sourceware dot org
Reporter: bill at broadley dot org
Target Milestone: ---
I tried the Systemtap on Rocky-8.4 (a recompile of RHEL-8.4) *AND* with the
current git branch and tried the nfsd-trace example.
Kernel/Env:
[root@nas-1-0 systemtap]# uname -a
