Michal Rostecki	3262f85925	bpf(doc): Hide docs of bindings ... Before this change, documentation of helper functions (defined by us, not bindings) were not visible, because `use gen::*` was overriding them with helpers coming from aya-bpf-bindings, which have the same names and no docs.

Michal Rostecki	7e2fcd1d6d	Support for fentry and fexit programs ... fentry and fexit programs are similar to kprobe and kretprobe, but they are newer and they have practically zero overhead to call before or after kernel function. Also, fexit programs are focused on access to arguments rather than the return value.

Thia Wyrod	b655cf973f	aya-bpf: remove unnecessary unsafe markers on map functions. ... Map lookup and deletion can yield stale keys and values by virtue of sharing a data structure with userspace programs and other BPF programs which can modify it. However, all accesses remain perfectly safe and will not cause memory corruption or data races.	3 years ago
