[Bug 1766754] Re: Linux kernel > 4.14 requires systemtap 3.2

[Tyler Hicks]

The Debian bug report mentions two upstream commits:

 https://sourceware.org/git/gitweb.cgi?p=systemtap.git;a=commitdiff;h=fbb26e17a
 https://sourceware.org/git/gitweb.cgi?p=systemtap.git;a=commitdiff;h=0643ca2b7

They both cherry-picked cleanly to the Bionic package so I prepared a
test build of systemtap with those two patches applied in this PPA:

 https://launchpad.net/~tyhicks/+archive/ubuntu/testing/+packages

Please let me know if the new package works for you and we can start the
process of getting the update into Ubuntu 18.04.

Bug description:
  Per https://sourceware.org/bugzilla/show_bug.cgi?id=22158 , Systemtap
  3.1 is broken on kernel versions > 4.14. It looks like they're aware
  of this in the debian package : https://bugs.debian.org/cgi-
  bin/bugreport.cgi?bug=892995 .  With Bionic Beaver about to ship with
  kernel 4.15 and systemtap 3.1-3, systemtap will be unusable on the LTS
  of Ubuntu.
