Bug Description

systemtap builds some module depending on linux kernel. The version 4.4 is not compatible with kernel 5.11.

This has been fixed upstream in https://sourceware.org/git/?p=systemtap.git;a=commit;h=ea81249b90b92a589d304c051efbc5bbad7ce073 and by comparing dates should be part of the 4.5 release.

Test command:
sudo stap -e 'probe begin { printf("Hello, World!\n"); exit() }'

Result:

Same problem in Ubuntu 21.10 on kernel 5.13.0-22. Basic Hello World program doesn't work.

@chfast @mukherjee-indraneel i think it's *extremely* unlikely - at least in the short term - that systemtap will become/remain usable in stable releases, especially when using HWE kernels; can I suggest that you try to use the backports process to provide a later (and hopefully working) version of systemtap to existing LTS release(s)?
