Dominique Martinet da60cdbcb7 libbpf: 1.2.0 -> 1.2.2
1.2.1: Bug fix release:

Single bug fix (#1) that fixes regression in `perf` tool caused by libbpf
resetting its custom catch-all `SEC()` handler on explicit
`bpf_program__set_type()` call.

Given setting custom `SEC()` handlers is rarely used and pretty
esoteric feature of libbpf, most users should not be affected.

1.2.2: One more fix:

 - Fix (#2) possible double-free in USDT-related libbpf code, which
happens when libbpf runs out of space in `__bpf_usdt_specs` map due
to having too many unique USDT specs. Running out of space can be
mitigated by bumping up `BPF_USDT_MAX_SPEC_CNT` define before including
`bpf/usdt.bpf.h` header in BPF-side code.
This will prevent the double-free as a side effect (and will make it
possible to successfully attach all requested USDTs), which is a
recommended work-around for libbpf versions prior to v1.2.2.
