Merge branch 'bpf_cubic'
Martin KaFai Lau says:
====================
This set adds bpf_cubic.c example. It was separated from the
earlier BPF STRUCT_OPS series. Some highlights since the
last post:
1. It is based on EricD recent fixes to the kernel tcp_cubic. [1]
2. The bpf jiffies reading helper is inlined by the verifier.
Different from the earlier version, it only reads jiffies alone
and does not do usecs/jiffies conversion.
3. The bpf .kconfig map is used to read CONFIG_HZ.
[1]: https://patchwork.ozlabs.org/cover/1215066/
v3:
- Remove __weak from CONFIG_HZ in patch 3. (Andrii)
v2:
- Move inlining to fixup_bpf_calls() in patch 1. (Daniel)
- It is inlined for 64 BITS_PER_LONG and jit_requested
as the map_gen_lookup(). Other cases could be
considered together with map_gen_lookup() if needed.
- Use usec resolution in bictcp_update() calculation in patch 3.
usecs_to_jiffies() is then removed(). (Eric)
