Well, only one of the patches, not strictly related to eBPF gave me some work:
commit 266fa2b22294909ddf6e7d2f8acfe07adf9fd978 Author: Arnaldo Carvalho de Melo <acme@redhat.com> Date: Thu Sep 24 11:24:18 2015 -0300
perf probe: Use existing routine to look for a kernel module by dso->short_name
And some patches came from Masami that I think were somehow related to things you reported, had to review/test/apply/push those as well.
