David Vernet 25c5e92d19 bpf/docs: Document struct task_struct * kfuncs ... bpf_task_acquire(), bpf_task_release(), and bpf_task_from_pid() are kfuncs that were recently added to kernel/bpf/helpers.c. These are "core" kfuncs in that they're available for use for any tracepoint or struct_ops BPF program. Though they have no ABI stability guarantees, we should still document them. This patch adds a new Core kfuncs section to the BPF kfuncs doc, and adds entries for all of these task kfuncs. Note that bpf_task_kptr_get() is not documented, as it still returns NULL while we're working to resolve how it can use RCU to ensure struct task_struct * lifetime.
