David Vernet 09b501d905 bpf: Remove bpf_kfunc_call_test_kptr_get() test kfunc ... We've managed to improve the UX for kptrs significantly over the last 9 months. All of the prior main use cases, struct bpf_cpumask *, struct task_struct *, and struct cgroup *, have all been updated to be synchronized mainly using RCU. In other words, their KF_ACQUIRE kfunc calls are all KF_RCU, and the pointers themselves are MEM_RCU and can be accessed in an RCU read region in BPF. In a follow-on change, we'll be removing the KF_KPTR_GET kfunc flag. This patch prepares for that by removing the bpf_kfunc_call_test_kptr_get() kfunc, and all associated selftests.
