This morning I upgraded my kernel package from kernel-4.14.18-300.fc27.x86_64 to kernel-4.15.3-300.fc27.x86_64. I am still using systemtap package version systemtap-3.2-2.fc27.x86_64. I am now getting script failures due to an apparent change in the kernel timer APIs. I believe this is related to upstream kernel git commit 919b250f8570618e84af544c3e18dad5210eb9b6 The exact error I am seeing: In file included from /usr/share/systemtap/runtime/transport/transport.c:65:0, from /usr/share/systemtap/runtime/linux/print.c:17, from /usr/share/systemtap/runtime/print.c:17, from /usr/share/systemtap/runtime/runtime_context.h:22, from /tmp/stap8wQmrP/stap_cbb6564739d1b29e282cdd69510ea1fe_57058_src.c:3085: /usr/share/systemtap/runtime/transport/relay_v2.c: In function ‘__stp_relay_timer_init’: /usr/share/systemtap/runtime/transport/relay_v2.c:154:2: error: implicit declaration of function ‘init_timer’; did you mean ‘init_timers’?

I'm not seeing this error on 4.15.3-300.fc27.x86_64 with HEAD systemtap. Have you got a small reproducer? I believe I fixed this in upstream commit 382a60e6a76ee and we just need to push a new version to f27 (but that reproducer would certainly confirm that).
Is it possible to include patch from upstream? https://sourceware.org/git/gitweb.cgi?p=systemtap.git;a=commitdiff;h=fbb26e17a Also upstream ticket: https://sourceware.org/bugzilla/show_bug.cgi?id=22551
I have applied that patch to f27 branch myself, and it works. Here is PR: https://src.fedoraproject.org/rpms/systemtap/pull-request/2 Koji build: https://koji.fedoraproject.org/koji/taskinfo?taskID=25231331
