hi,

It contains 2 changes that improove search performance for livepatch
and bpf.
v3 changes:
- fixed off by 1 issue, simplified condition, added acks [Song]
- added module attach as subtest [Andrii]
v2 changes:
- reworked the bpf change and meassured the performance
- adding new selftest to benchmark kprobe multi module attachment
- skipping patch 3 as requested by Zhen Lei
- added Reviewed-by for patch 1 [Petr Mladek]
thanks,
jirka
